摘要
针对AES密钥管理中存在的安全性不高和RSA不适合大数据量加/解密的缺陷,为保障用户的敏感信息以及BLE门禁设备的重要数据,本文提出了采用AES与RSA混合的加密体制。利用AES算法来加/解密敏感数据,RSA算法来加/解密AES算法的密钥。然后,采用DBMS外层加密方式和字段级的加密粒度,在BLE门禁管理系统中实现对"敏感数据"的加/解密处理,以及混合加密体制下密钥的管理,保证了数据的安全性与可靠性。
There are flaws existing in the data encryption,such as imperfect security of the AES key management and RSA misfitting for large quantity encryption and decryption. In order to guarantee the user＇s sensitive information and important data of BLE access equipment,hybrid encryption system combining AES with RSA is put forward in this paper. Firstly,AES algorithm is used to encrypt and decrypt the sensitive data,then RSA algorithm is applied to encrypt and decrypt the key of AES algorithm. Finally,the DBMS outer layer encryption and field- level granularity encryption are used to realize encryption and decryption of the sensitive data in the BLE entrance guard management system,and management of the key in hybrid encryption. These ensure the security and reliability of the data.
