omnet++密钥预分配方案的仿真，基于哈希算法的eg方案的改进-omnet++ simulation of the key pre-distribution scheme, eg based on the hash algorithm to improve the program

用OMNET++4.0编写的RC4算法，可直接移植。（注：不是文档，只能在omnet++4.0下使用）-Prepared with OMNET++4.0 RC4 algorithm can be directly transplanted. (Note: not a document, only in omnet++4.0 use)
