摘　　要：针对传统单一加密技术无法满足特定场合的安全性要求以及部队武器装备数据的涉密性质,提出了一种基于国密SM2椭圆曲线公钥加密算法与SM4分组加密算法的混合加密方案。与传统单一加密方案对比,该方案具有更高的安全性。实验验证结果表明,方案扩散性最高可达到87.2%,安全性高,且加密解密耗时相比其他方案增加了19%。对结果的对比分析证明了方案在安全性和时间复杂度之间取得了良好的平衡,有一定的可行性与实用价值。A hybrid encryption scheme based on state secret SM2 elliptic curve public key encryption algorithm and SM4 block encryption algorithm was proposed to solve the problem that the traditional single encryption technology could not meet the security requirements of specific occasions and the confidentiality nature of military weapon and equipment data. Compared with traditional single encryption scheme, this scheme had a higher security. Experimental verification results showed that the scheme had a maximum diffusivity of 87.2%, high security, and the encryption and decryption time increased by 19% compared with other schemes. The results showed that the scheme achieved a good balance between security and time complexity, and had certain feasibility and practical value.
