Compilers undermine cryptographic software security

SCM feed for Latest

Researchers have identified vulnerabilities in compilers, particularly GCC, that can compromise the security of cryptographic software. The issue arises from how these compilers optimize code, potentially undoing constant-time implementations that are designed to prevent timing attacks. Timing attacks allow attackers to infer sensitive information, like passwords, based on how long it takes a system to respond to requests. This is a significant concern for developers of cryptographic software who rely on constant-time operations to secure user data. Companies that use GCC for their software development should be aware of these vulnerabilities and consider reviewing their code to ensure it remains secure against timing analysis attacks.
