A cryptographic protocol possesses separability if the participants can choose their keys independently of each other. This is advantageous from a key-management as well as from a security point of view. This paper focuses on separability in group signature schemes. Such schemes allow a group member to sign messages anonymously on the group’s behalf. However, in case of this anonymity’s misuse, a trustee can reveal the originator of a signature. We provide a generic fully separable group… CONTINUE READING
