Abstract: The hashing function is one of the basic foundations of the cryptography. It widely used in data integrality and identity authentication. This paper Present a technique of using IDEA grouping cipher arithmetic to build a hashing function and with double key system to achieve identity authentication and digital signature.

摘要： 散列函数是密码学的基础要素之一，主要应用方向是数据完整性校验和身份认证技术。本文利用ＩＤＥＡ分组密码算法构造一散列函数，结合双密钥体制，在传输明文信息时，通过数字指纹，实现了一种认证和数字签名的方案。
