	abstract = {An implementation of the hash functions SHA-256, 384 and 512 is presented, obtaining a high clock rate through a reduction of the critical path length, both in the Expander and in the Compressor of the hash scheme. The critical path is shown to be the smallest achievable. Synthesis results show that the new scheme can reach a clock rate well exceeding 1 GHz using a 0.13?m technology.},

	abstract = {After recalling the basic algorithms published by NIST for implementing the hash functions SHA-256 (384, 512), a basic circuit characterized by a cascade of full adder arrays is given. Implementation options are discussed and two methods for improving speed are exposed: the delay balancing and the pipelining. An application of the former is first given, obtaining a circuit that reduces the length of the critical path by a full adder array. A pipelined version is then given, obtaining a reduction of two full adder arrays in the critical path. The two methods are afterwards combined and the results obtained through hardware synthesis are exposed, where a comparison between the new circuits is also given.},
