Poly1305 is a polynomial hash function designed by Bernstein in 2005. Presently, it is part of several major platforms, including the Transport Layer Security protocol. Vectorised implementation of Poly1305 was proposed by Goll and Gueron in 2015. The authors provide some simple algorithmic improvements to the Goll–Gueron vectorisation strategy. Implementation of the modified strategy on modern Intel processors shows marked improvements in speed for short messages.
