摘　　要：针对数据文件需要加密存储的问题,研究采取了基于IDEA算法的软件加密手段来解决。IDEA算法是一种分组密码算法。描述IDEA算法,介绍软件的加解密流程,通过采用二项分布的拟合检验对基于IDEA算法的软件进行统计性能测试,测试结果证实算法在数据软加密方面的有效性。IDEA is applied to a software encryption problem where data safeguard are required. IDEA is a block cipher algorithm. The algorithm of IDEA are firstly described. Secondly, the encryption procedure and dencryption precedure are discussed respectively. Thirdly, the statistic performance testing of IDEA cipher is put up by χ2 testing of binary distributing. Finally, the results show the effectiveness of IDEA.
