摘要
基于分区架构的嵌入式高安全系统对于不同安全级别分区的跨平台、多用户处理和共享提出了更高的安全性要求。针对这一要求,设计了PCS信息流控制策略,通过对分布式中处于不同节点的通信双方进行身份认证、接入控制,对接收到的不同安全级别的信息采用不同的密钥和算法进行加解密,以保证节点间数据在传输过程中的机密性和完整性。
Embedded high assurance systems on partition architecture put forward the higher demands for cross-platform,multi-user processing and sharing of different security levels of partition. Aim at this request,information flow control policies of PCS( Partition Communication System) are designed. Authentication and access control of both sides of communication. Multiple encryptions and decryptions with different encryption algorithms and crypto keys according the security level of the data,to ensure confidentiality and integrity of data during inter-system transmission.
