摘要： PROBLEM TO BE SOLVED: To provide a high tamper-resistive encrypting method, its decrypting method, and an apparatus for achieving it. SOLUTION: The encrypting method divides a plaintext data 100 into a plurality of blocks, and encrypts the plurality of block data (intermediate texts 10, 20) to generate cipher texts 30. For encrypting the block data, a part of the data of different blocks is used as an encrypting key for the data of the blocks. For example, the encrypting key may be a part of the data of blocks adjacent to the blocks to be encrypted. Thus formed cipher text 30 is decrypted to obtain plaintext data 100, using the encrypting key used at encrypting. COPYRIGHT: (C)2007,JPO&INPIT
摘要翻译：要解决的问题：提供高抗窜改加密方法，其解密方法和实现该方法的装置。解密方式：加密方法将明文数据100划分为多个块，并对多个块数据（中间文本10,20）进行加密，生成密文30.为了对块数据进行加密，部分数据使用不同的块作为块的数据的加密密钥。例如，加密密钥可以是与要加密的块相邻的块的数据的一部分。使用加密时使用的加密密钥对这样形成的密文30进行解密以获得明文数据100。版权所有（C）2007，JPO＆INPIT
