SCA电台内部消息安全管理机制的设计与验证

Implementation and Verification of Secure Message Management Mechanism in SCA Radio

SCA电台一般基于CORBA组件模型来设计业务、控制、信号处理、硬件抽象以及人机相关的各种组件,其分布式处理架构使得电台内部的业务数据难以集中管控,导致业务极不安全[S1],为解决该问题进行了深入的探索,研究了SCA软件架构及其安全架构,提出了电台内部业务消息的SCA组件化处理流程,给出了消息内容的安全集中管理机制以及消息存放位置单独传送的设计方法,并在SCA电台中对组件设计和安全集中管理机制进行了实现与测试验证。

SCA Radio based on CORBA component model is generally used to design the components relat-ed to traffic, control, signal processing, hardware abstraction and HMI. This distributed processing archi-tecture would result in hard implementation of centralized control on the traffic data within the radio,and thus lead to some safety problems. In order to solve these problems, SCA software architecture and related security architecture are discussed, the message processing procedures for traffic data by SCA components proposed,and the design methods for centralized security management mechanism and location information transferring mechanism for message given in this paper. These methods are implemented,tested and veri-fied by SCA components.
