Identity management with trust relationship and privacy preservation

Achieving trust relationship with privacy preservation is one of the key purposes of identity management. A novel identity management model is proposed to build trust relationship among different parties through identity validation and authentication. A two-way handshake process with two variants is introduced to implement strong mutual authentication between users and service providers without revealing real world identities of users. Security analysis and experiments show that confidentiality, integrity, usability and privacy protection ability for both users and service providers are enhanced effectively with good user experience and high performance.
