New authenticated key distribution scheme and secure broadcast scheme
Shengbo Xu, Xinmei Wang · 2002
We make use of [2nl+1,nl+1] systematic MDS code over GF(2/sup m/), m being a positive integer no less than 64, to construct a new authenticated key distribution scheme with the ability to correct t errors, which may distribute simultaneously a session key k among n users. To protect the integrity of message, a message authentication check symbol is also introduced into the new scheme.
