Abstract
A method, system and computer readable medium for establishment of cryptographic secrets is disclosed. Illustratively, the method includes obtaining a first input share based on a hybrid key establishment method, obtaining a second input share from a key distribution network, and deriving, from the first input share and the second input share, a shared secret for use in cryptographic communication between an initiator and a respondent.
Claims22
A method for establishment of cryptographic secrets, the method comprising:
- obtaining a first input share from a key distribution network (KDN);
- and
- obtaining a second input share based on a hybrid key establishment method;
- deriving, from the first input share and the second input share, a shared secret for use in cryptographic communication between an initiator and a respondent.
A method for associating two entities comprising deriving shared secrets for use in cryptographic communications between the two entities, the method comprising:
- based on a common shared base secret, deriving:
- a key secret,
- a link secret,
- an authentication secret.
A system for cryptographic communications, the system comprising at least two endpoints and a key distribution network comprising a plurality of key distribution hubs connected to one another, at least one of the endpoints comprising a process and memory, the memory storing computer executable instructions that when executed by the processor cause the endpoint to perform operations comprising:
- obtaining a first input share from the key distribution network;
- obtaining a second input share based on a hybrid key establishment method;
- and
- deriving, from the first input share and the second input share, a shared secret for use in cryptographic communication between an initiator and a respondent.
A non-transitory computer readable medium comprising computer executable instructions for cryptographic communications, the computer executable instructions when executed by a processor causing the processor to perform operations comprising:
- obtaining a first input share from a key distribution network (KDN);
- and
- obtaining a second input share based on a hybrid key establishment method;
- deriving, from the first input share and the second input share, a shared secret for use in cryptographic communication between an initiator and a respondent.
