The aim of the thesis is to implement the digital signature on Database As a Service to ensure efficient data security. The implementation and validation of digital signature raises several challenges such as the selection of suitable algorithm for signing, hashing and storing the digital signature key pair and key exchange mechanism. We generate a key pair for every individual user and store the pair in centralized repository. We conduct a complete evaluation on efficiency of digital signature with respect to many aspects comparing with other encryption techniques. During the evaluation we propose a banking system as a case study for the empirical validation of our approach. The main challenging part of the thesis is maintaining data integrity, and confidentiality even though its a time consuming process. The interesting feature of digital signature application is, it doesnt allow cloud database administrator to view the sensitive field data of the database.
