SecDBaaS with SQL Operations over Encrypted Database for Real Time Data in Cloud Environment

The cloud computing has reap its prevalence by anything as a service (Xaas).The three major services are Software as a Service, Platform as a Service and Infrastructure as a service. The database is a maturing service nowadays. The database stored at the cloud should be encrypted and operations on the encrypted data to be performed in order to reduce the passive attack. The passive attack exists inside the system but it does not affect the data, sends information to the intruder. The Snooping of data can be reduced by performing SQL query operations over encrypted database. In accordance to encrypt and perform SQL query operations over database the various algorithms are used. This project proposes to perform SQL operation over encrypted database. The various encryption algorithms which are used to perform SQL operations over encrypted database are random encryption, homomorphic encryption, Deterministic Encryption, Order Preserving Encryption and MAC. The time complexity is used to measure the performance of the algorithm which can be used to perform SQL operations over encrypted database.
