基于AES和模运算的密文索引方案
Cryptograph index scheme based on AES and modular arithmetic
摘要
Abstract
Adding secure index to the encrypted data is an available method handling the problem of executing queries on encrypted data in outsourcing scenarios. Aiming at the construction of secure index, this paper proposed a scheme of wrap-round partition cryptograph index (WPCI) based on advanced encryption standard (AES) and modular arithmetic. It obtained the index by encrypting attribute value using AES and modulo operation, which made the index partially order-preserving. This scheme reduced the useless decryption load of the users in equality queries extremely while supporting range queries effectively. Furthermore, storage burden evaluation and security analysis of WEPI show that storage burden is acceptable, and it meets the basic needs of privacy constraints.关键词
