Security Attributes of Key Agreement Protocol Sample Clauses

Security Attributes of Key Agreement Protocol. The followings are the security requirements of key agreement protocols, some of which are specific to ID-based key agreement protocol. Known-key security: Each run of the key agreement protocol should generate an unique and independent session key. An adversary must have non-negligible advantage on compromising future session keys, even though it compromised past session keys. Forward secrecy: An adversary must have non-negligible advantage on compromis- ing past session keys, even though it compromised long-term private keys of one or more participants. The notion of forward secrecy can be further extended to the following two types of secrecy. – Perfect forward secrecy: The forward secrecy must be preserved even if long- term private keys of all the participants involved are compromised. – PKG forward secrecy: The forward secrecy must be preserved even if the master key of the PKG is compromised. Key-compromise resilience: An adversary must have non-negligible advantage on im- personating others to A, even if it has compromised A’s private key. Unknown key share resilience: An adversary must have non-negligible advantage on coercing others into sharing a key with other entities when it is actually sharing with a different entity. Key control: An adversary must have non-negligible advantage on forcing the session key to be a preselected value. The PKG forward secrecy is a stronger notion of perfect forward secrecy that ap- plies only to ID-based protocols. In ID-based cryptosystems, if the master key is com- promised, an adversary can compute all the participants’ private keys. Therefore, If ID- based key agreement protocol satisfies PKG forward secrecy, then it also satisfies per- fect forward secrecy too. However, the opposite is not true. We can also define perfect PKG forward secrecy in multiple PKG environment. This secrecy implies that forward secrecy is preserved even if all the master keys of PKGs are compromised.
