Extended Group Key Transfer Protocol for Authentication Using DES Based on Secret Sharing in Cloud

The Key establishment protocol also needs to provide security, confidentiality, authentication and integrity for session keys to be sent messages to any system in network. There are two types of key establishment protocols one is key transfer protocol and other one is key agreement protocol. Key transfer protocol rely on a mutually trusted Key Generation Center (KGC) to select session keys and transport session keys to all communication entities secretly. Most often, KGC encrypts session keys under another secret key shared with each entity during registration. A secret sharing scheme is a method which distributes shares of a secret to a set of participants in such a way that only specified groups of participants can reconstruct the secret by poling they share.
