In most cases, manufacturers store Security IC Embedded software in the non-volatile non-programmable memories (ROM).

However, you can also store the supplements of the embedded software in the non-volatile programmable memories, for example E2PROM.



The Security IC Embedded Software consist of Hard-coded Security IC Embedded Software which is usually stored in ROM and Soft-coded Security IC Embedded Software stored in Flash Memory or E2PROM.

Which are the main Threats to Security IC?

The common types of cyber threats facing individuals and organizations operating Security IC systems consist of:

· Manipulation of Data

This may include any data, consisting of code, saved or operated on by the security integrated circuit.

In this type of cyber-attack, an attacker is capable of altering a significant block of data. Manipulation of data include threats like T.Abuse-Func, T.Malfunction and T.Phys-Manipulation.

· Manipulation of the Security IC

In this case, the attacker is in a position to deliberately alter or deactivate the behavior of a particular function in a way which facilitates exploitation.

The threats in this type of attack consist of T.Abuse-Func, T.Malfunction and T.Phys-Manipulation.

· Disclosure of Data

Here, an attacker is practically capable of determining a significant block of data.

The threats in this type of Security IC attack include T.Leak-Inherent, T.Abuse-Func, T.Leak-Forced and T.Phys-probing.

· Cloning of the Security IC

The greatest degree security fear in the execution setting is the replication of the functional behavior of the secure IC on its command and physical interface.

The main objective of functional behavior cloning is to;

  1. Create a functional copy of the embedded software of the security IC.
  2. Disclose, interpret and utilize the confidential user data stored in the secure IC, and
  • Create and make a functional counterfeit of the security IC utilizing inputs of the primary IC.

What is the importance of Logic Encryption in Security IC Design?

Also referred to as obfuscation, logic encryption is a famous technique for protecting a security IC design against hardware Trojans and IP piracy.

It involves the insertion of extra gates to the design to conceal the original functionality.

The gates are commonly known as key-gates since they are linked to a series of key-inputs.

When a wrong key is entered into the key-inputs, the Security IC generates the wrong results. On the other hand, if you enter the right activation key, the IC gets unlocked and functions correctly.

Logic encryption is normally carried out on a netlist prior to delivery to the untrusted foundry. After fabrication, the security IC is sent back to the designer who activates it by inserting the right activation key.

Typically, the key is saved and protected in a tamper-proof memory.

Although a malicious attacker can retrieve the encrypted design of the Security IC in the foundry, reverse engineering it is impossible because the activation key is unknown.

For that reason, the design stays safe against malicious modification and IP piracy.

What is Unclonable Security IC?

Encrypted IC

Encrypted IC

Unclonable security IC are made in such a manner that it creates exclusive signatures that can be applied in chip authentication.

This type of security IC is manufactured through variations of the manufacturing process to ensure easy differentiation among other identical ICs.

Unclonable Security IC allows you to proactively, effortlessly and logically guard your intellectual property and product using a solution that is impenetrable by hostile physical attacks.

The Unclonable type of security IC is extremely secure.

This is because the safeguarded set of cryptographic devices consisting of:

  • True random number generator
  • Asymmetric hardware engine
  • Distinctive 64-bit ROM identification number together with other components

Additionally, it is exceptionally cost-effective, dependable over process temperature and straightforward to implement.

Integrating unclonable security IC into the design of customers is simple and it comes with a predetermined function command kit that constitutes cryptographic operations.

In relation to protection benefit, this type of security ICs can simplify or eliminate the necessity for sophisticated key management, which you can directly employ in cryptography.

For example, some Unclonable Security ICs employ ChipDNA technology to shield IoT systems. Nevertheless, incorrect use of this type of Secure IC can result in bypassing ordinary authentication or encryption within a computer system.

How do you perform Security Rule Checking in Security IC Design?

Design Security Rule Check is a system that is incorporated in the standard design flow of a Security IC.

It is to examine its vulnerabilities and evaluate the security at different phases of design processes.

These may include:

  • Physical design
  • Design-for-test insertion
  • Gate-level netlist
  • Register transfer level, among other steps

In order to use the DSeRC framework one requires an exhaustive record of vulnerabilities for Security IC.

The vulnerabilities are then linked with metrics and rules, to allow for quantitative measurement of each variable.

The DSeRC system enables the systematic identification of security issues and vulnerabilities prior to tape-out.

This allows you to modify the design to tackle the issues or incorporate proper countermeasures.

To spot and assess vulnerabilities linked to Security ICs, you need to integrate Design Security Rule Check into the ordinary design flow of the IC.

The DSeRC will read the design files and user input data constraints.

It will also examine the Security IC for susceptibilities at all phases of abstraction, that is, Register-transfer level, gate and physical layout level.

To ensure the quantitative measurement of security of each design, every vulnerability is related with a group of metrics and rules.

At Register Transfer Level, the DSeRC framework evaluates the security IPs and will give feedback so that discovered security problems can be taken care of.

After tackling the RTL security vulnerabilities, the design will be amalgamated to gate level and then you insert design-for-debug (DFD) and design-for-test (DFT) structures.

Thereafter, the Design Security Rule Check system will examine the netlist of the gate level for security vulnerabilities. A similar procedure will go on even for the physical layout design.

Security rule checking enables you to pinpoint and take care of security vulnerabilities during the earliest design stages.

This makes Security ICs more secure as well as significantly reducing the cost and time for development by minimizing the time-to-market challenge.

In addition, the DSeRC system facilitates a quantitative comparison of the various implementation of similar design.

Thus allowing performance optimization without undermining security.

However, the framework will require some input from you. For instance, you need to specify the security assets depending on the design target specifications.

What is Split Fabrication of Security IC?

Split manufacturing arrangement

Split manufacturing arrangement

Split fabrication is a technological method for manufacturing outsourced Security ICs.

The concept is to divide (split) an integrated circuit into various “fragments” that are built in different foundries.

So, none of the foundries have a picture of the final Secure IC.

In split manufacturing, the Security IC design layout is partitioned into Back End of Line (BEOL) layers and Front End Of Line (FEOL) layers.

The layers are then built independently in different foundries.

The BEOL layers comprise of the top metal layers while the FEOL layers comprise of transistors together with lower metal layers.

After fabrication, the BEOL and FEOL wafers get aligned and joined together applying either optical, mechanical or electrical alignment methods.

Finally, the resultant Security IC is tested after the successful integration of the BEOL and FEOL wafers.

The metal layers’ asymmetrical nature facilitates split fabrication of Secure IC.

Are there Challenges in Spilt Manufacturing of Security IC?

Yes, Security IC manufacturers face some difficulties when using a split fabrication technique.

Let’s look at the main challenges in split manufacturing of the Security Integrated Circuit.

Security IC Platform

Security IC Platform

  • Transporting the BEOL wafer to the FEOL foundry or transferring the BEOL and FEOL wafers to the System-on-Circuit integrated may pose a challenge.

The wafers are very thin and might delaminate or break during transportation.

  • Alignment of the BEOL and FEOL layers and expansion of die area to hold alignment structures pose another challenge.
  • Split fabrication of Security IC may as well have an effect on the integrity of the signal, the timing of the transmission that span the BEOL and FEOL layers, among other design for manufacturability elements.

Additionally, proximity attack is another potential challenge to split the manufacturing of Security IC. When ordinary route and place tools are employed for physical design, the closeness of gates within the untrusted tier will disclose information.

It is the information regarding their connectivity within the hidden tier.

Full layout randomization, though it comes with high cost, is the recommended solution to this challenge.

Does Split Fabrication offer Advantages over Complete Security IC Fabrication?

The main advantage of split manufacturing of Security IC is that it enhances the security of an integrated circuit.

This is because the BEOL and FEOL layers are built independently and combined after fabrication.

This prohibits one foundry (particularly the FEOL foundry) from having complete control over the IC.

For example, in the absence of the BEOL layer, it is not possible to identify and insert Trojans in ‘safe’ locations within the circuit.

Also, it’s not possible to counterfeit the designs of the IC in the absence of the BEOL layers.

In addition, split fabrication is less costly compared to the complete fabrication of the Security IC.

Is Security IC the same as Authentication IC?

Authentication IC system

Authentication IC system

Authentication IC is a function-specific type of Security IC which is instrumental in authenticating operations or data in a system.

This Security IC type offers drop-in answers for challenge and response authentication.

The challenge-response authentication between the peripheral and host system facilitates the identification of unauthorized and authorized parts.

Authentication ICs come with on-chip engines crucial in ECC-P256 and SHA-256 cryptography in addition to:

  • 8 KB of secure EEPROM for certificates
  • Application data
  • Private/public key pairs
  • Private keys

These features enable it to support both asymmetric and symmetric authentication mechanisms. In addition, most Authentication ICs have the ability to dynamically create private/public key pairs necessary in high-level validation protocols.

How do you Test the Quality of Security IC?

The test of Security ICs is critical to guarantee its quality.

The examination is instrumental in preventing out-of-spec and defective integrated circuits from getting into the market.

You conduct quality testing by comparing the noted output of the Security IC with the anticipated test feedbacks for a batch of test patterns.

An automatic test pattern production algorithms help in the generation of the test patterns.

The main objective of available test pattern production algorithms is to attain greater fault coverage at reduced test costs.

In an effort to minimize the test data size, the algorithms disclose the maximal information associated with the internal circuit structure.

This is achieved by sensitizing the interior outputs nets as practical as possible.

Also, this leads to unintentional leakage of the circuits embedded secrets as well.

What are the Features of Security IC?

  • End-to-end, provides best-of-breed solutions
  • Root of trust: Secure storage of secret (secret key, unique ID) and Secure Boot
  • Security Monitoring: Life-cycle management, Secure Debug
  • Strong tamper resistance: resilience to perturbation attacks and fault injection
  • Guarantee data protection

How do you Choose Security Integrated Circuit?

Here are some of the factors to consider when selecting a Security IC:

Security ICs

Security ICs

· Absolute Maximum Ratings

These are the ratings of the security IC that should never be surpassed during the application of the device.

Exceeding absolute maximum ratings may result in serious damage, shorten the lifespan or destroy the Security integrated circuit.

You should choose a Security IC with ratings above your operation limits because fabricators will not take responsibility for an IC that exceeds their absolute maximum ratings.

· Power Dissipation

Power dissipation of the Security IC is a very important consideration because the IC should not overheat and also it should conserve batteries.

Excess heat may damage your Security IC or may temporarily degrade its quality while they are heated.

Therefore, when selecting a Security IC it is important you factor in its power dissipation. This is to ensure it will not surpass a maximal chip temperature or drain power unnecessarily.

· Temperature Range and Performance Variation with Temperature

Secure ICs are expected to function to specification within a range of temperatures.

The features of the ICs and hence their accuracy will vary based on the temperature.

Due to this fact, it is essential to the temperature coefficients and temperature range when choosing a Security IC.

· Security

Hacking aimed at IoT gadgets is increasing, a threat that is particularly relevant to integrated circuits used in security systems.

As a result, you should go for a Security IC that implements layers of security like physical security and cryptography.

Choose an IC which has been validated to the modern security standards or employs MCUs having on-chip safe hardware.

· Hardware Architecture

The packaging of security IC directly affects its size and performance, with the most common type being Dual In-line packaging.

Quad flat packs cover a brooder surface but reduced vertical space, and small outline transistors boast of a small footprint.

Wafer-level chip-scales are relatively smaller and absorb in more processing power though they are more costly to fabricate.

Flat no-lead packages are good in the diffusion of heat.

While ball grid arrays (BGAs) ensure high performance because of the compact package though they are equally costly to fabricate.

Do Security ICs have Memory?

Yes, security ICs have memory.

It is where the initialization data and configuration data associated with the running of the security functionality and the IC dedicated software are coded.

The memories can be classified into non-volatile programmable memories such as flash memory or E2PROM and non-volatile non-programmable memories (ROM).
