Title:
Parallelized hashing via j-lanes and j-pointers tree modes, with applications to SHA-256
Authors: Shay Gueron
Abstract:The j-lanes tree hashing is a tree mode that splits an input message to j slices, computes j independent digests of each slice, and outputs the hash value of their concatenation. The j-pointers tree hashing is a similar tree mode that receives, as input, j pointers to j messages (or slices of a single message), computes their digests and outputs the hash value of their concatenation. Such modes have parallelization capabilities on a hashing process that is serial by nature. As a result, they have performance advantage on modern processor architectures. This paper provides precise specifications for these hashing modes, proposes a setup for appropriate IV’s definition, and demonstrates their performance on the latest processors. Our hope is that it would be useful for standardization of these modes.
