摘要: 基于无证书公钥密码技术的铁路通信网访问控制,能够在显著降低系统开销、快速响应网络访问控制的同时,解决加密访问控制信息的公钥的真实性无法保证的问题。研究过程中使用了无证书公钥密码(CL-PKC,Certificateless Public Key Cryptography)技术和基于角色访问控制(RBAC,Role-Based Access Control),保证系统不被非法操作,相较于使用证书的密码技术,减少系统确认信息真实性的时间。此研究使得铁路通信网的访问控制实现了信息真实性和效率的充分兼顾,能够简单、高效地实现对铁路通信网内信息的保护,满足应用要求。Abstract: Access control of railway communication network based on certificateless public key cryptography can greatly reduce system overhead and respond to network access control quickly, and solve the problem that the authenticity of the public key for encrypting access control information cannot be guaranteed. In the process of research, this article used Certificateless Public Key Cryptography(CL-PKC)and Role-Based Access Control(RBAC) to ensure that the system would not be operated illegally. Compared with the use of certificate based cryptography, it reduced the time for the system to confirm the authenticity of information. This research makes the access control of railway communication network implement the full consideration of information authenticity and efficiency, and can realize the protection of information in railway communication network simply and efficiently, and meet the application requirements.
