In order to solve the vulnerability problem of the traditional encryption mechanisms, the honey encryption mechanism was applied to three types of private data including identity card numbers, mobile phone numbers and bank card passwords to protect data storage security. Firstly, the principle of honey encryption was analyzed and discussed, and a distributed-transforming encryptor for honey encryption system was designed. Then, the message space was abstracted, and the system was implemented and its performance was evaluated. The performance overhead problem was found and an enhanced mechanism was proposed. The message spaces with uniformly/non-uniformly distribution were taken into account and also used for symmetric encryption algorithm and public key encryption mechanism in the design and implementation of honey encryption. Through the proposed design, system implementation and experimental results of honey encryption, the following conclusions are drawn:1)due to the performance issue, honey encryption is more suitable for a small message space instead of a large one; 2)the design of message space needs to be considered comprehensively, which can not bring fingerprint characteristics, otherwise it can not solve the vulnerability problem of brute-force attack; 3)the protection ability of honey encryption is different with the application; 4) the implementation of honey encryption has to be customized for different applications.
