New Method Improves AES Performance in Homomorphic Encryption
/ 1 min read
🦛 New approach enhances AES performance in fully homomorphic encryption. Researchers have introduced a novel method called “hippo” to improve the execution speed of the AES algorithm within the TFHE framework, achieving a single-core execution time reduction from 46 seconds to 32 seconds. This advancement addresses the longstanding challenge of balancing boolean- and byte-oriented operations in AES, which has hindered practical fully homomorphic encryption (FHE) performance. The study highlights the versatility of the proposed techniques, suggesting their applicability to other algorithms facing similar operational tensions. As AES gains renewed attention in the FHE community, particularly with NIST’s upcoming call on threshold cryptography, these findings mark a significant step forward in optimizing FHE capabilities.
