数据库中基于密文角色的密钥管理方案

Design of Security Key Management Scheme Based on Encryption Role in Database

设计一种高效安全的管理方案来解决数据库中加密密钥的分配与管理问题。通过对多种密钥管理机制的分析,结合数据库角色管理设计了一种基于密文角色的密钥管理方案。分析了基于密文角色的密钥管理方案的安全性,并在数据库中对其进行了应用实现。基于密文角色的密钥管理方案极大方便了密文访问权限的管理,极大提高了密钥管理的效率。

Designing an effective safe management scheme to resolve the database encryption key for the allocation and management issues. By analyzing various key management mechanism,a key management scheme based on encryption role is designed. Security of key management scheme based on encryption role was analyzed,key management scheme based on encryption role was actualizd in database. Key management scheme based on encryption role greatly facilitated access jurisdiction management and greatly improved the key management efficiency.
