Description:

Critical Infrastructure Protection (CIP) mechanisms are commonly based on complex models of interdependencies between the many operators in our critical infrastructure. Particularly due to the rapid emergence of new cyber-threats, the sharing of incident information is indispensable for the functioning of such mechanisms. However, the high sensitivity of this information prevents operators from sharing it.

CRIPTIM introduces the new paradigm of "cryptographic incident management" for CIP that ensures data confidentiality with cryptographic guarantees, thereby reducing the operators' fears of information leakage. The underlying idea is to monitor and analyze incident data in the encrypted domain, while an alarm is set off only when a certain failure or alarm state is detected. The subsequent alarm resolution is facilitated through novel access control mechanisms for the selective disclosure of alarm-related information. CRIPTIM realizes this paradigm by developing novel custom-tailored cryptographic techniques in Secure Multiparty Computation, Homomorphic- and Functional Encryption, as well as Oblivious RAM. The intended technology will, for the first time, allow external parties, like intelligence agencies, to feed threat-related topsecret information into the monitoring system which may be the missing piece for the early detection of potentially major disasters. CRIPTIM sets the foundations for this innovative approach to CIP and contributes to an effective and confidential incident management that leads to a more secure and reliable critical infrastructure.
