摘要

Recently, Wang et al. proposed a (t,n) threshold signature scheme with (k,l) threshold shared verification and a group-oriented authenticated encryption scheme with (k,l) threshold shared verification. However, this article will show that both the schemes violate the requirement of the (k,l) threshold shared verification. Further, two improvements are proposed to eliminate the pointed out security leaks inherent in the original schemes.
