Single-Trace Side-Channel Security Analysis of Homomorphic Encryption

#security #engineering #computer

Side-channels pose a significant threat to cybersecurity, as hardware can inadvertently leak sensitive information, such as cryptographic keys, through side-channel attacks, enabling adversaries to compromise mathematically-secure encryption systems. Homomorphic encryption, in particular, has emerged as a critical tool for securing sensitive data in modern computing environments. As the demand for secure and privacy-preserving computation grows, understanding and mitigating vulnerabilities within these systems becomes paramount.
In this talk, Dr. Aydin will present our research on single-trace side-channel analysis of homomorphic encryption, including the first power-based side-channel attack  on homomorphic encryption. Dr. Aydin will also discuss additional single-trace vulnerabilities and explore proactive measures to strengthen homomorphic encryption against these attacks. Finally, Dr. Aydin will touch on the impact of optimization in software implementations, providing insights into potential vulnerabilities introduced by compiler optimization.
