摘要
In regard to the communication security of open networks, authenticated key management agreements are able to provide confidentiality, integrity, and verification so as to establish a more secure and fair digital rights management mechanism. For this reason, this paper, aiming at authentication key management agreements, tends to provide a security study on the application of authentication key management agreements, covering the establishment, analysis, design, security study, and performance optimization in various environments. Based on present public key schemes, such as public key cryptography, identity-recognized cryptography, and undocumented cryptography, it aims to establish an authenticated key management agreement suitable for various application environments. Using the one-way transmission in identity-recognized cryptography or undocumented cryptography for formulating practical and effective security models, it tends to establish the one-way authentication key agreement for both parties. Based on the design of single authentication key, an authentication key agreement for the undocumented public key cryptography is proposed to design a security model for the secure and high-efficiency undocumented two-party authentication key agreement. Under random oracle model and standard model, the security of the undocumented two-party authentication key agreement is authenticated. Furthermore, aiming at the computational efficiency, communication efficiency, and key exchange frequency of group key management agreements, this paper aims to propose a method for dynamic membership. Besides, regarding the secure communication environment in different application backgrounds, such as the network applications of Grid, P2P, and ad-hoc, it would propose practical group key agreements for networks and multi-node communications to promote the security of group key management and to facilitate the computation of agreements and the optimization of communications.
