Design and analysis of authenticated key establishment protocols Saha, Mounita In the current age of information communication, security is one of the most important concern which is attracting a lot of attention from the research community. Cryptography is a pivotal method to offer security to communication of various information. Authentication and key establishment protocols are cryptographic techniques that are the first steps to set up a secure communication by authenticating the users involved and establishing a secure key among them. The key can subsequently be used to offer various security services. In this thesis various new protocols for authentication and key establishment are proposed in order to enhance efficiency and security of communication. In the design of key establishment protocols, the use of cryptographic primitives requiring less computations are preferred to increase efficiency. Particularly, due to the popularity of applications in heterogeneous environments, protocols having less computational burden on the low power users have become essential. One of the design goals of the protocols proposed in the thesis is to provide an asymmetric computational pattern to enhance the overall efficiency. The security analysis of the protocols have been performed under provable security model.
