Most of the existing authentication schemes for mobile communication are static in nature, and principally dependent on strength of authenticating identifiers for users' identity. The acceptance of all the transactions of a user under a single authentication level is vulnerable. The authors propose a novel Transaction Based Authentication Scheme (TBAS) for mobile communication using cognitive agents. The proposed approach provides range of authentication based on mobile transaction sensitivity, and users' behaviors. The TBAS uses mobile agents to gather user behaviors, and static agents for detecting transaction sensitivity, user history analysis, and for choosing appropriate authentication actions.
