for the resource-constrained characteristics of the smart phone,this paper proposes a lightweight smart phone security authentication protocol based on social network against the problem of PKI-based public key encryption for authentication demanding lots of terminal resource.This protocol combines with the features of users having small number of contacts,makes use of symmetric encryption instead of the original asymmetric encryption,distributes symmetric key using the Kerberos protocol,and then uses the BAN logic to conduct a formal analysis of protocol security.Experimental results show that the proposed protocol in the smart phone is faster,with less demand for resources,and has longer life for the terminal.
