Abstract

Recovering from malicious attacks in survival database systems is vital in mission-critical information systems. Traditional rollback and re-execute techniques are too time-consuming and can not be applied in survival environments. In this paper, two efficient approaches - transaction dependency based and data dependency based are proposed. Comparing to transaction dependency based approach, data dependency recovery approaches need not undo innocent operations in malicious and affected transactions even some benign blind writeson bad data item speed up recovery process.
