| 摘 要： | 本文介绍了一种可以应用于敏感信息保护的密码学方法--保留格式加密。保留格式加密是一种全新的密码学技术,将一种特定格式的明文加密成相同格式的密文,因此密文的类型和长度与明文相同,不需要改动数据在数据库中的存储结构,降低数据库应用系统改造的成本,可以成为敏感信息保护的有效方法,具有较广的应用前景。

| Abstract: | The paper introduces a cryptology method which can be used to protect sensitive information.The method is format-preserving encryption (FPE).FPE is a new cryptology method,it can encrypt a plaintext to a ciphertext which has the same format,and as a result,the ciphertext has the same type and length with the plaintext as plaintext.FPE will be the popular method to protect the sensitive information,because it will not change the structure of database and can reduce the cost of software upgrade,so it has wide applications. |
