Group Signature Schemes Based on Elliptic Curve Discrete Logarithm
Hong Zhong · Computer Technology and Development · 2007
Introduces group signature and its security character,and proposes two group signature schemes based on elliptic curve discrete logarithm.The theory analysis shows that the schemes are correct,secure and efficient,and satisfy the group security character.Where,for the first scheme,it is very simple to authorize the signature,which fits the small group,and for the second scheme,it is irrespective between the signature size and the group size,which fits the large dynamic group.
