Abstract
Apparatus and method to negotiate parameters of a policy in establishment of a peer-to-peer link are described herein. In an embodiment, a security policy is negotiated in establishment of a peer-to-peer link in a wireless mesh network.
Claims20
A method comprising:
- generating a first request message from a first party to a second party, the first request message including an identifier of the first party, an identifier of the second party, and a ciphersuite list of the first party, the ciphersuite list containing parameters supported by the first party and arranged as an ordered list;
- receiving a second request message from the second party, the second request message including the identifier of the second party, the identifier of the first party, and a ciphersuite list of the second party, the ciphersuite list of the second party containing parameters supported by the second party and arranged as an ordered list;
- and
- selecting a parameter from a comparison of the ciphersuite list of the first party and the received ciphersuite list of the second party, the selection using a rule in which the identifiers of the two parties determine the selection, the selected parameter being a negotiated parameter of a policy in establishment of a peer-to-peer communication link between the first party and the second party.

An apparatus comprising:
- a memory cache to store a session authentication key and a ciphersuite list of parameters of a policy supported by the apparatus;
- an authenticated identity;
- and
- processing circuitry to control negotiation of the policy in establishment of a peer-to-peer communication link with another device including selection of a parameter as a negotiated parameter of the policy, the selection of the parameter derived from a comparison of the ciphersuite list with a ciphersuite list received from the other device in a message containing the ciphersuite list of the other device and an authenticated identity of the other device, the selection based on a rule in which the authenticated identities determine the selection.
1 more element
A system comprising:
- a memory to store a session authentication key and a ciphersuite list of parameters of a policy supported by the system;
- an authenticated identity;
- processing circuitry to control negotiation of the policy in establishment of a peer-to-peer communication link with another system including selection of a parameter as a negotiated parameter of the policy, the selection of the parameter derived from a comparison of the ciphersuite list with a ciphersuite list received from the other system in a message containing the ciphersuite list of the other system and an authenticated identity of the other system, the selection based on a rule in which the authenticated identities control the selection;
- and
- a substantially omnidirectional antenna to communicate with the other system.
