多级变长异或实时加解密及校验方法

摘要

In order to realize the requirment of the speed, safety which for the real-time business bank encryption and the automation management, this paper proposes a method that combines the secret key with the real-time cleartext, which can realize the multilevel variable-length xor encryption of the cleartext, the method can also realize the real-time encryption and decryption of the data, verify the completion of the data, manage the secret key automatically.%为了实现银行实时业务数据加密提出的速度、安全性以及自动化管理的加密要求,本文提出以密钥和实时明文互结合的方式对明文进行多级变长异或加密,实现数据的实时加解密、数据完整性验证以及密钥的自动化管理.
