摘要
针对临近空间信息系统覆盖范围广、平台相对静止从而导致的信息易被监听、截获甚至篡改的问题，提出一种基于签密技术的临近空间链路的通信密钥更新方案，并从正确性、机密性和抗中间人攻击三个方面对方案进行分析，论证了该方案能够确保临近空间信息传输的机密性和完整性。
Aimed at the problem of information can be easily monitored, intercepted and cap- tured, even tampered with because of the wide coverage area and the platform relatively motion- less of near space information system, a communication key update method of near space link based on signcryption technique is proposed in this paper, the method is analyzed from three as- pects of correctness, confidentiality and anti-attack of intermediary, and it is proved that the method can insure the confidentiality and integrity of near space information transmission.
