MANAGEMENT OF CRYPTOGRAPHIC KEYS

摘要

MANAGEMENT OF CRYPTOGRAPHIC KEYS A method for simplifying key management in situations where unique cryptographic keying relationships are required end-to-end between pairs of parties and a symetric encryption algorithm is to be used. It is useful in cases where the parties come from disjoint subsets of the total population of parties. The method provides some of the characteristics of a public key crypto system (PKS) utilising the public identities of the parties as part of the key, but lacks the property of PKS which allows a party to independently generate a secret key which is known only to that party.
