AVON: A fast Hash function for Intel SIMD architectures

Abstract

In this paper, we propose a hash function that takes advantage of the AES-NI and other Single-Instruction Multiple-Data operations on Intel x64 platforms to generate digests very efficiently. It is suitable for applications in which a server needs to securely hash electronic documents at a rate of several cycles/byte. This makes it much more efficient for certain applications than SHA-2, SHA-3 or any of the SHA-3 finalists. On the common Sandy Bridge micro-architecture, our hash function, AVON, has a throughput of 2.65 cycles per byte while retaining a high degree of security.
