摘要: 针对现有VoIP加密算法实现相对复杂、计算量大、系统性能消耗明显的情况,提出了一种适合于重视实现成本低、速度快、最小性能消耗的商业级应用轻量级VoIP加密算法。该算法本质上仍然是对称钥体系,但由动态小算法库组成,采用有记忆的改变每次加密的算法组合的原理,并在保证一定安全性的基础上解决了传统的必须要公钥密码体制传送密钥的问题,实现简单、速度快,计算量小。Abstract: The popular VoIP encryption algorithms have the disadvantages of high computational complexity and huge system capability consumption. To solve this problem, this paper proposes a new VoIP encryption algorithm suitable to civilian commercial applications with low cost, high speed, and low capability consumption. This algorithm uses the combination of encryption arithmetic operations and solves the problem that the secret key must be transmitted by public key cipher system.
