A Practical Collision-Based Power Analysis on RSA Prime Generation and Its Countermeasure
IEEE Access, 2019 We analyze the security of RSA prime generation implemented on embedded devices by a practical power analysis attack. Unlike previous differential power analysis-based attack on primality tests of RSA prime generation exploiting the deterministic ...

On the Design of Secure and Fast Double Block Length Hash Functions [PDF]
, 2008 In this work the security of the rate-1 double block length hash functions, which based on a block cipher with a block length of n-bit and a key length of 2n-bit, is reconsidered.

Security of signed ELGamal encryption [PDF]
, 2005 Assuming a cryptographically strong cyclic group G of prime order q and a random hash function H, we show that ElGamal encryption with an added Schnorr signature is secure against the adaptive chosen ciphertext attack, in which an attacker can freely use

Mechanical Stress Evolution in Polycrystalline Ge Thin Films Under MeV Ion Irradiation
Advanced Materials Interfaces, EarlyView.Irradiation of polycrystalline Ge thin films with 1.8 MeV Au ions alters residual stress through defect generation and lattice expansion. Increasing fluence drives progressive lattice disorder and eventual amorphization. Polycrystalline Ge resists amorphization longer than crystalline Ge, as grain boundaries facilitate defect diffusion, significantly ...

Preimage and pseudo-collision attacks on 29-step SM3 hash function with padding
Tongxin xuebao, 2014 The security of SM3 hash function was revaluated by using the meet-in-the-middle attack. The preimage and pseudo-collision attack on 29-step SM3 hash function (from the 1-st step) with padding was presented.

Improvement on a Masked White-Box Cryptographic Implementation
IEEE Access, 2020 White-box cryptography is a software technique to protect secret keys of cryptographic algorithms from attackers who have access to memory. By adapting techniques of differential power analysis to computation traces consisting of runtime information ...

A Symbolic Intruder Model for Hash-Collision Attacks [PDF]
, 2006 In the recent years, several practical methods have been published to compute collisions on some commonly used hash functions. In this paper we present a method to take into account, at the symbolic level, that an intruder actively attacking a protocol ...
