摘要
EPON通信系统采用点对多点通信模式,而这种通信模式使得OLT与ONU通信过程中存在非法接入、窃听、伪造等安全威胁,针对这种情况,提出了一种基于SHA-256散列算法及AES加密算法的认证、密钥更新、加密技术来解决上述安全威胁,并对方案中认证、会话密钥生成和密钥更新各阶段进行了详细分析。
EPON communication system using a point-to-multipoint communication mode, Which is faced with a series of security threats due to its communication mode, such as illegal access, eavesdropping, imper- sonation and other security threats. The paper proposed a kind of authentication, key updating,encryption technique, based on the SHA-256 hash algorithm.Furthermore, this paper analyzes the certification stage, the session key generation and key update stage in detial.
