Bouncy Castle Java 安全漏洞

Bouncy Castle Java is an open-source encryption algorithm developed by Legion of the Bouncy Castle Inc. There were security vulnerabilities in Bouncy Castle Java versions from 2.17.3 to 1.84. These vulnerabilities stemmed from non-constant time comparisons, which could lead to the exposure of the...

A Comparative Performance Evaluation of Kyber, Sntrup761, and FrodoKEM for Post-Quantum Cryptography

Post-quantum cryptography PQC aims to develop cryptographic algorithms that are secure against attacks from quantum computers. This paper compares the leading postquantum cryptographic algorithms, such as Kyber, sntrup761, and FrodoKEM, in terms of their security, performance, and real-world...

SUSE CVE-2023-1732

When sampling randomness for a shared secret, the implementation of Kyber and FrodoKEM, did not check whether crypto/rand.Read returns an error. In rare deployment cases error thrown by the Read function, this could lead to a predictable shared secret. The tkn20 and blindrsa components did not...
