An Adaptive Multiparty Protocol for Secure Data Protection

To better protect information systems, computation time data protection needs to be considered such that even when the system is partially compromised, the security of the system is still assured. Secure multiparty computation approaches provides a possible solution for computation time data protection, but are too costly (in communication) to be practical. In this paper, we design an adaptive multi-level secure computation algorithm with the goals of reducing the average communication overheads. The adaptive algorithm runs a less secure protocol to reduce the communication overhead when there is no threat. The system adapts to a more secure but less efficient protocol when security threat is detected. Thus, the system yields better performance at normal execution time while still assures security protection at the presence of security threats.
