Abstract: The traceability is one of the core requirements for group signature schemes. Group signature schemes based on the bilinear mapping were proposed.
In this paper, we point out that the efficient group signature schemes con- structed by Cheng et al. has no traceability due to their improper use of bilinear ...
It is shown that Cheng-Zhu-Qiu-Wang's group signature schemes have no traceability property due to their improper use of a bilinear mapping in their ...
The traceability is one of the core requirements for group signature schemes. Group signature schemes based on the bilinear mapping were proposed.
Unlike the group signature schemes considered in this paper, however, their scheme does not support traceability or ... skaya's (DCL) group signature scheme from ...
