Abstract
Web 2.0 describes a collection of web-based technologies which share a user-focused approach to design and functionality. Under the supporting of Web 2.0 technologies (e.g., HTML5), there are many applications, e.g., seamless reader over equipment, collaborative editing with multiple members, portable multimedia over devices, on browsers become feasible. In one of our previous works, we proposed a two-factor authentication with key agreement scheme for web-based collaborative systems. This paper further extends it to have secure group communication for web-based collaborative systems. With the proposed mechanism, members of the collaborative work could be share their messages easily and co-work securely. In order to provide high efficiency and data confidentiality, this paper presents an efficient group key agreement scheme for group members. The group members can join/leave the group easily.
