Enhanced HMAC structure based burst header authentication design for optical burst switched networks

Security Evaluation of the Enhanced Key Generation Algorithm of Hashing Message Authentication Code

“…Further, HMAC's cryptographic strength basically relies on the quality and size of the key, hash output length in bits, and the cryptographic strength of the chosen hash function [6], [7]. One of the well-known hash algorithms is MD5 due to its extensive availability and shorter length [8].…”
