Secure Group Key Management Approach Based upon N-dimensional Hyper-sphere
Secure group communication systems become more and more important in many emerging network applications. For a secure group communication system, an efficient and robust group key management approach is essential. In this paper, a new group key management approach with a group controller GC using the theory of hyper-sphere is developed, where a hyper-sphere is constructed for the group and each...
متن کاملProvably secure group key exchange
The rapid and promising development of applications and communication systems designed for groups of participants like groupware, computer supported collaborative work systems, or digital conference systems implies exigence of mechanisms providing adequate security properties. These mechanisms can be designed based on the foundations of cryptography. Group key exchange protocols are multi-party...
متن کاملProvably Secure Key Exchange: An Engineering Approach
We promote an engineering approach to design of provably secure key exchange protocols. Using the model of Canetti and Krawczyk we present a systematic method to arrive at efficient and practical protocols with proven security and illustrate its use with existing building blocks. We further show a dual approach which allows protocols with known features to be ‘reverse engineered’, thereby allow...
متن کاملTowards Provably Secure Group Key Agreement Building on Group Theory
Known proposals for key establishment schemes based on combinatorial group theory are often formulated in a rather informal manner. Typically, issues like the choice of a session identifier and parallel protocol executions are not addressed, and no security proof in an established model is provided. Successful attacks against proposed parameter sets for braid groups further decreased the attrac...
