Secure Multiparty Key Agreements

This book aims and considers the problem of group key management in dynamic setting for Resource Constraint Networks. In Chapter 1 we present introduction and summary of the Book. In Chapter 2 we discuss and analyze the requirements for key establishment which handles dynamic groups. we then investigate in Chapter 3 the cryptographic foundations. We take a closer look at back ground of elliptic curve cryptography; cryptographic assumptions based on discrete logarithms. Chapter 4 presents DACGKA a complete family of GKA protocols for SGC namely initial group key agreement Join and Leave protocols for membership change in a model with authenticated links. In Chapter 5 demonstrates Security Analysis and Security model. Beyond that we define a formal model for GKA protocols. In Chapter 6 we study about the results and comparative analysis in which communication and computation efficiency of the protocols are analyzed and compared with popular ECDH and DH based protocols. Finally in Chapter 7 we summarize the work in the form of conclusion and give an outlook on open problems and possible research directions in the form of future work.
