Intel Random Number Generator
https://www.rambus.com/intel-random-number-generator/Good cryptography requires good random numbers. This paper evaluates the hardware-based Intel Random Number Generator (RNG) for use in cryptographic applications. Almost all cryptographic protocols require the generation and use of secret values that must be unknown to attackers. For example, random number generators are required to generate public/private keypairs for asymmetric (public key) […]
Differential Power Analysis
https://www.rambus.com/differential-power-analysis/Abstract: Cryptosystem designers frequently assume that secrets will be manipulated in closed, reliable computing environments. Unfortunately, actual computers and microchips leak information about the operations they process. This paper examines specfi c methods for analyzing power consumption measurements to and secret keys from tamper resistant devices. We also discuss approaches for building cryptosystems that can […]
Introduction to Differential Power Analysis and Related Attacks
https://www.rambus.com/introduction-to-differential-power-analysis-and-related-attacks/As part of Cryptography Research’s ongoing cryptosystem research activities, we have been analyzing how to improve security of portable cryptographic tokens, including smart cards. Over the past year and a half, we have been working with the smart card vendor community to address attacks we have developed including Simple Power Analysis, Differential Power Analysis, […]
Timing Attacks on Implementations of Diffie-Hellman, RSA, DSS, and Other Systems
https://www.rambus.com/timing-attacks-on-implementations-of-diffie-hellman-rsa-dss-and-other-systems/An academic paper introducing timing attack cryptanalysis. Many elements of timing attacks are relevant to DPA. Abstract: By carefully measuring the amount of time required to perform private key operations, attackers may be able to find fixed Diffe-Hellman exponents, factor RSA keys, and break other cryptosystems. Against a vulnerable system, the attack is computationally […]
