Abstract:

The security mechanism of DaaS (Database as a service) is mainly addressed. DaaS can solve the data security problem using encryption method. A new mo
del 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.

Key words: data security, database as a service, NetDB2 technology, secret sharing
