SCV (select, cross, and variation): Data Encryption


A new technical paper "RSCV: Reversible Select, cross and variation architecture in quantum-dot cellular automata." Abstract "In the past few years, CMOS semiconductor has been a growing and evolving technology in VLSI. However, due to the scaling issue and some other constraints like heat generation, high power consumption QCA (quantum cellular automata) emerged as an alternate and enhan... » read more

Hardware Countermeasures Benchmarking against Fault Attacks


Abstract "The development of differential fault analysis (DFA) techniques and mechanisms to inject faults into cryptographic circuits brings with it the need to use protection mechanisms that guarantee the expected level of security. The AES cipher, as a standard, has been the target of numerous DFA techniques, where its security has been compromised through different formulations and types of... » read more

A novel technique for random number generation using CMOS image sensor


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


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


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


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
