A novel technique for random number generation using CMOS image sensor
By Technical Paper Link - 04 Apr, 2022 - Comments: 0

Academic paper from Thamirabharani Engineering College, India. Abstract "Random Number Generators (RNGs) have been used in several traditional fields such as simulation, gaming, cryptography, etc. Random numbers are used in cryptography to generate passwords. The strength of a password depends not just on its length and complexity but mainly on its unpredictability. Strong passwords lower t... » read more

DPA Countermeasures Done Right
By Bart Stevens - 03 Mar, 2022 - Comments: 0

In the late nineties, Paul Kocher, Josh Jaffe, and Ben Jun published a paper that caused many across industry sectors to reconsider what cryptographic implementations should look like. They described an exploit wherein an adversary could extract secrets from a device by analyzing the power consumption or electromagnetic emittance from the device when it was executing cryptographic operations. S... » read more

A high speed processor for elliptic curve cryptography over NIST prime field
By Technical Paper Link - 17 Feb, 2022 - Comments: 0

Abstract "Elliptic curve cryptography (ECC), as one of the public key cryptography systems, has been widely applied to many security applications. It is challenging to implement a scalar multiplication (SM) operation which has the highest computational complexity in ECC. In this study, we propose a hardware processor which achieves high speed and high security for ECC. We first present a three... » read more

QUAC-TRNG: High-Throughput True Random Number Generation Using Quadruple Row Activation in Commodity DRAM Chips
By Technical Paper Link - 18 Nov, 2021 - Comments: 0

Abstract "True random number generators (TRNG) sample random physical processes to create large amounts of random numbers for various use cases, including security-critical cryptographic primitives, scientific simulations, machine learning applications, and even recreational entertainment. Unfortunately, not every computing system is equipped with dedicated TRNG hardware, limiting the applicat... » read more

AKER: A Design and Verification Framework for Safe and Secure SoC Access Control
By Technical Paper Link - 12 Nov, 2021 - Comments: 0

Abstract: "Modern systems on a chip (SoCs) utilize heterogeneous architectures where multiple IP cores have concurrent access to on-chip shared resources. In security-critical applications, IP cores have different privilege levels for accessing shared resources, which must be regulated by an access control system. AKER is a design and verification framework for SoC access control. AKER builds ... » read more

Power/Performance Bits: Oct. 19
By Jesse Allen - 19 Oct, 2021 - Comments: 0

Post-quantum crypto chip Researchers at the Technical University of Munich (TUM) designed and had fabricated an ASIC to run new encryption algorithms that can stand up to quantum computing. “Ours is the first chip for post-quantum cryptography to be based entirely on a hardware/software co-design approach,” said Georg Sigl, Professor of Security in Information Technology at TUM. “As a... » read more

Implementing An AES Cipher On Application-Specific Processors
By Sriram Sharma Kalluri - 07 Oct, 2021 - Comments: 0

In the previous blog post, “Embedded Security Using Cryptography”, we looked at how cryptography can be used for securing assets in embedded systems and ensure confidentiality, integrity and authenticity, or in short “CIA”. In this blog, we will explore the Advanced Encryption Standard (AES) and how to implement an AES engine on Cadence Tensilica Xtensa application-specific processors. ... » read more

Navigating The Seas Of FIPS 140-2 CMVP With Certified Root Of Trust And TRNG IP
By Bart Stevens - 07 Oct, 2021 - Comments: 0

No captain worth his salt would set sail without an experienced navigator at his side. Likewise, when navigating the FIPS 140-2 CMVP process, it’s extremely valuable to have a partner that has already successfully made the journey. More specifically, working with a partner that offers CMVP-certified IP can streamline the process and increase the success of achieving CMVP certification of chip... » read more

The Battle For Post-Quantum Security Will Be Won By Agility
