Abstract
A method and apparatus that establish secure communications between two stations. The apparatus includes a low power communication processor and a host processor in a sleep mode. The low power communication processor receives a protocol message to initiate a communication. The protocol message includes an encrypted cryptographic identity token and triggers a wake-up event in order to wake up the host processor according to a result of identity a freshness checks performed by the low power communication processor.
Claims21
A method comprising:
- establishing an identity exchange via a network with a remote device to generate an identity context message that includes an encrypted cryptographic freshness identity token;
- placing a host processor into a sleep mode while maintaining presence on the network with a communication processor;
- while operating the host processor in a sleep mode, receiving from a sending device a protocol message with the communication processor to initiate a communication, wherein the protocol message includes the identity context message;
- checking identity and freshness of the protocol massage based at least in part on the identity context message, wherein checking a freshness of the protocol massage comprises comparing a value of an incoming protocol message a counter with a received protocol messages counter;
- and
- waking up the host processor if the identity and freshness check of the protocol message is passed.
An apparatus, comprising:
- a host processor;
- and
- a communication processor coupled with the host processor, wherein the communication processor is configured to:
- establish an identity exchange via a network with a remote device to generate an identity context message that includes an encrypted cryptographic freshness identity token, wherein the communication processor is further configured to check a freshness of the protocol massage by comparing a value of an incoming protocol message a counter with a received protocol messages counter;
- maintain a presence on the network while the host processor is in a sleep mode;
- receiving from a sending device a protocol message to initiate a communication, wherein the protocol message includes the identity context message;
- check identity and freshness of the protocol massage based at least in part on the identity context message;
- and
- wake up the host processor if the identity and freshness check of the protocol message is passed.
An article of manufacture comprising a non-transitory machine readable medium having instructions stored thereon that, if executed, result in:
- establishing an identity exchange via a network with a remote device to generate an identity context message that includes an encrypted cryptographic freshness identity token;
- placing a host processor into a sleep mode while maintaining presence on the network with a communication processor;
- while operating the host processor in a sleep mode, receiving from a sending device a protocol message with the communication processor to initiate a communication, wherein the protocol message includes the identity context message;
- checking identity and freshness of the protocol massage based at least in part on the identity context message, wherein checking a freshness of the protocol massage comprises comparing a value of an incoming protocol message a counter with a received protocol messages counter;
- and
- waking up the host processor if the identity and freshness check of the protocol message is passed.
