一种新的软件无线电安全下载策略

针对软件无线电设备在软件下载中重新配置过程的安全问题,设计了一种新的软件无线电安全下载算法。该算法在每次执行下载任务时收发双方包括了一个不同的随机数,对通信双方的身份进行认证,并分别对下载信息摘要和密文进行混淆处理。通过对设计实例的安全性分析,证明该算法能够大大提高软件下载的安全性。与典型的加密算法进行比较,该算法具有很强的抗攻击能力。

A New Secure Scheme of Software Defined Radio Download

Aiming at the secure problem during the parameters re-configuration of the software download,a new safety download scheme is designed,in which a random number is brought into the algorithm while executing the download task. And in the course of encryption/decryption,the abstract of message and the cipher are confused by the random numbers. So the security of software download is enhanced greatly. At last,by comparing to other typical encrypt algorithms,the proposed algorithm has strong resisting-attack ability.
