CK Security Model Sample Clauses

CK Security Model. CK security model [8] presents definition of SK-security, allows for modular design and analysis of key exchange protocol, which simplifies the difficulty of design and analysis of security protocol. The security definition is based on the concept of indistinguishability The attacker model follows the unauthenticated-links model (UM) that the attacker is a (probabilistic) polynomial-time machine with full control of the communication lines between parties. In addition, the attacker can have access to secret information via session exposure attacks of three types: session-state reveal, session-key queries, and party corruption. The first type of attack is directed at a single session which is incomplete and the result is that the attacker learns the session state of that particular session. A session-key query can be performed against an individual session after completion and the result is that the attacker learns the corresponding session-key. Finally, party corruption means that the attacker learns all information in the memory of that party; in addition, from the moment a party is corrupted all its actions are totally controlled by the attacker. Sessions can be expired in the model of CK. From the time a session is expired the attacker is not allowed to perform a session-key query or a state-reveal attack against the session, but is allowed to corrupt the party that holds the session. Protocols that ensure that expired sessions are protected even in case of party corruption are said to enjoy “perfect forward secrecy”. For defining the security of a KE protocol, CK follows the indistinguishability style of definitions that the “success” of an attacker is measured via its ability to distinguish the real values of session keys from independent random values. When the attacker chooses the test session it is provided with a value υ which is chosen as follows: a random bit b is tossed, if b = 0 then υ is the real value of the output session-key, otherwise υ is a random value chosen under the same distribution of session-keys produced by the protocol, but independent of the value of the real session key. After receiving υ , the attacker may proceed with the regular actions against the protocol; at the end of its run the attacker outputs a bit b' . The attacker succeeds in its attack if (1) the test session is not exposed, and (2) the probability that b = b' is significantly larger than1/ 2 . Note that the attacker is allowed to corrupt a party to the test sess...
