Application of Identification Cryptography in IMS Network

Summary

As a unified core network architecture platform for fixed network and mobile in the future, the security problem of IP Multimedia Subsystem (IMS) cannot be ignored.The identification cryptography technology is based on the bilinear paired identification cryptographic algorithm, uses the user identity as the public key, realizes the natural binding of the user identity and the public key, and builds a relatively simplified and low-complexity public key cryptography system.etc. have natural advantages.Through the research on the distributed identification and password mechanism, based on the IMS network, the security distribution of private keys, terminal network authentication, service key negotiation and other workflows are designed to effectively solve the security protection problem of the IMS network. Finally, the security of the scheme is evaluated and analyzed..

3 Conclusion

IP Multimedia Subsystem (IMS) is a set of frameworks proposed by the 3rd Generation Partnership Project (3GPP) to support IP multimedia services. It is based on the Session Initiation Protocol (SIP)) to complete the call control function and realize the creation, management and termination of multimedia services.IMS realizes the integration of multiple services through the IP bearer network, forming a new-generation softswitch platform that separates control and bearer, and separates service and control.The choice of IMS as the unified core network architecture for fixed and mobile networks has been the consensus of major standards organizations in the field of mobile communications at home and abroad.However, due to I
