Group signature schemes allow a group member to sign messages anonymously on behalf of the group. During last decade, group signature schemes have been intensively investigated in the literature and applied to various applications. Especially, as noted in [3], the complexity of member deletion stands in the way of real world applications of group signatures. In this paper, we propose a group si...

In this chapter we describe the development of the Individual Group Member Interpersonal Process Scale (IGIPS), a group therapy process measure based on an interpersonal, interactionally oriented approach to group psychotherapy. We delineate the nature of the group theory underlying the IGIPS as well as the entire developmental history of the instrument. The rationale for the creation of the me...

We propose an interesting efficient member ID-based group signatures, i.e., verification of output from algorithm OPEN run by the group manager does not have to refer to a registration table (acting as certification list). The proposal is free of GM-frameability, i.e., secret key of member is not escrowed to GM, which is unique among all known member ID-based group signatures as far as we know....

Aspect-Oriented Software is a broad term, encompassing several different views on the nature of the aspects and the relationships between aspects and objects. Attaching aspects to objects is one way of forming a group. While there are many useful patterns of interaction, e.g. strategies [2], decorators, and the like, we focus on groups in which the group delegates to members to obtain behavior ...
