网际空间认证框架及相关量子技术

Framework of Authentication in Cyberspace and its Related Quantum Technology

认证是实现网际空间安全保障的重要技术之一。本文将网际空间中的认证技术归为身份认证、消息认证、混合认证和新兴应用认证四类,对其认证需求和主要技术进行了系统说明,同时也涉及了相关量子技术进展情况,试图构建一个认证技术框架。文中提到的四个量子认证方案显示出它们与传统认证技术的对应关系。

Authentication is one of the major technologies for cyberspace assurance. To build a framework of authentication technologies in cyberspace, the paper classifies the authentication technologies as four categories, identity authentication, message authentication, hybrid authentication, and authentication for emerging applications. It also gives a systematic description of authentication requirements and of the main technologies. The paper includes both the traditional authentication and those based on quantum cryptography. By means of four quantum authentication schemes, which are the earlier research results, the correspondence between quantum authentication schemes and those traditional ones is illustrated.
