A flaw was found in the Linux kernel's jitterentropy cryptographic module. A long-held spinlock during entropy collection could cause parallel readers to stall. This issue allows a local attacker to trigger a Denial of Service DoS by causing contention for the shared lock, making the system...

When RSA Fails: Exploiting Prime Selection Vulnerabilities in Public Key Cryptography

This paper explores vulnerabilities in RSA cryptosystems that arise from improper prime number selection during key generation. We examine two primary attack vectors: Fermat's factorization method, which exploits RSA keys generated with primes that are too close together, and the Greatest Common...
