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.
