摘　　要：针对指挥信息系统软件面临的安全威胁和多种攻击手段,提出一种基于加密锁的指挥信息系统软件防护方法.该方法将计算机硬件特征信息作为密钥存储在加密锁中,并通过加密锁的全球唯一序列号将加密锁和软件、计算机进行一一绑定,将软件核心算法通过代码隔离的方法保存在加密锁中,并使用一定的代码混淆技术提高软件攻击者的破解难度.将该方法用于多个项目软件,结果证明其可以有效保证软件安全.Nowadays, CaISR System faces multiple threats and attack measures. Therefore, a method based on en- cryption lock is proposed to protect C4ISR System. Hardware feature information is written into encryption lock as the key, then make a consistent one-to-one match among each software, each computer and each encryption lock through the world＇s only serial number of encryption lock. The key algorithm is saved in the encryption lock based on code isolation. And also obfuscated code is used to increase the difficulty of software attack. The method has applied in some projects, and the results show that it can effectively ensure the safety of the software.

关 键 词：指挥信息系统 软件保护 加密锁 代码隔离
