摘要 针对DaaS中加密技术的局限性问题,研究了数据库服务模型(DaaS:Database-as-a-Service)中的数据安全机制,提出了基于NetDB2的最小私密属性共享模型(NetDB2-MAMS:NetDB2-Minimum Attribute Multi-Secret Sharing),通过获取最小共享属性集合,应用秘密共享技术保护用户数据。实验结果表明,该方法可以有效地保护DaaS中的隐私数据,同时避免了数据加密和解密的高成本问题。 The security mechanism of DaaS (Database-as-a-service) is mainly addressed. DaaS can solve the data security problem using encryption method. A new model based on NetDB2-MAMS (NetDB2-Minimum Attribute Multi-Secret Sharing) is presented, user data can be protected by getting minimum shared attribute set and using secret sharing technology. Experiments show that the model can protect the privacy of DaaS and avoid the cost of encryption and decryption.
