Abstract: PURPOSE: An idea based broadcast encrypting method in a sensor network environment is provided to drastically reduce the amount of calculation of entire sensor nodes by reusing pairing calculation requiring large amount of calculation in a encrypting and demodulating process. CONSTITUTION: A system generating a bilinear pairing function, a master secret key, and an open key is set up. A secret key for a sensor node is generated and distributed. Open information is shared after the sensor nodes are arranged. A message is encrypted using the ID of a receiving sensor node. The encrypted message is demodulated using the secret key of the receiving sensor node.

Abstract: The present invention relates to an intrusion tolerant technology and, more specifically, to an intrusion tolerant system which periodically checks the performance of the system and expands, contracts, or replaces clusters to prevent a decrease in quality of service (QoS). According to the present invention, an active cluster conversion structure, which is an intrusion tolerant architecture, has significantly improved performance in comparison with a cluster having a fixed size by using a unique active technology of combining the redundancy of virtual servers in a cluster with a virtualization technology.
