Unified Identity Authentication Platform for Campus Network Users Based on SOA

摘要

Quantum communication can realize the detectability and unconditional security of eavesdropping based on Heisenberg Uncertainty Principle and quantum states no-cloning principle the quantum secure and secret communication field gains high attention of all countries throughout the globe. For the failure to detect and eavesdrop of the existing SIP security scheme and the vulnerability of the classical cryptosystem when facing quantum computation attack, the work in the Thesis includes three points: 1. propose the idea to combine quantum secure communication mechanism with SIP it that it can overcome the problem of the traditional SIP security mechanism and the security of high-grade SIP communication by virtue of the physical characteristics of quantum; 2. design the quantum identity authentication and key negotiation scheme suitable for carrier-class SIP network process based on three-particle W state and conduct analysis for its performance; 3. it is not necessary to prepare and distribute new W state during the key negotiation stage but use the W state recovered after the success of identity authentication so as to effectively save quantum entanglement resources. The performance analysis in simulation experiment indicates that the scheme can counter impersonation attack and eavesdropping attack so as to effectively improve the security of SIP.
