Method, system and apparatus for updating encryption keys on a mobile communication device
A system and method for managing key generation for a mobile communication device ( 116 ). In one embodiment, the system includes means ( 304 ) for receiving at the mobile communication device ( 116 ) a key generation request ( 506 ) during a communication session ( 530 ) between the mobile communication device ( 116 ) and a first communication node ( 106 ). The system further includes means ( 216 ) for storing a record relating to the key generation request ( 506 ) in a storage structure ( 216 ) within the mobile communication device ( 116 ) and means ( 302, 218 ) for initiating a key generation session ( 534 ) responsive to the key generation request ( 506 ) upon completion of the communication session ( 530 ) with the first communication node ( 106 ).
1 . A mobile communication device comprising:
a storage structure operable to store data relating to key generation requests received by the mobile communication device;
a logic structure operable to identify a key generation request received during a communication session with a first communication node and to store in the storage structure a record related to the key generation request; and
a processing unit operable to initiate a key generation session responsive to the key generation request upon completion of the communication session with the first communication node.
2 . The mobile communication device as recited in claim 1 wherein the communication session with the first communication node is a key generation session.
3 . The mobile communication device as recited in claim 1 wherein the communication session with the first communication node is conducted via a wireless connection.
4 . The mobile communication device as recited in claim 1 wherein the logic structure is a transport stack.
5 . The mobile communication device as recited in claim 1 wherein the first communication node is a remote services server.
6 . The mobile communication device as recited in claim 1 wherein the storage structure is a queue.
7 . The mobile communication device as recited in claim 1 wherein the device further comprises a key generation module.
8 . A method for managing key generation for a mobile communication device, the method comprising the steps of:
receiving at a mobile communication device a key generation request during a communication session between the mobile communication device and a first communication node;
storing a record relating to the key generation request in a storage structure within the mobile communication device; and
initiating a key generation session responsive to the key generation request upon completion of the communication session with the first communication node.
9 . The method as recited in claim 8 wherein the communication session with the first communication node is a key generation session.
10 . The method as recited in claim 8 wherein the communication session with the first communication node is conducted via a wireless connection.
11 . The method as recited in claim 8 wherein the communication session with the first communication node is an over-the-air provisioning session.
12 . The method as recited in claim 8 wherein the first communication node is a remote services server.
13 . The method as recited in claim 8 wherein the storage structure is a queue.
14 . The method as recited in claim 8 further comprising the step of generating an encryption key using a key generation module disposed within the mobile communication device.
15 . A system comprising:
means for receiving at a mobile communication device a key generation request during a communication session between the mobile communication device and a first communication node;
means for storing a record relating to the key generation request in a storage structure within the mobile communication device; and
means for initiating a key generation session responsive to the key generation request upon completion of the communication session with the first communication node.
16 . The system of claim 15 wherein the communication session with the first communication node is a key generation session.
17 . The system of claim 15 wherein the communication session with the first communication node is conducted via a wireless connection.
18 . The system of claim 15 wherein the communication session with the first communication node is an over-the-air provisioning session.
19 . The system of claim 15 wherein the first communication node is a remote services server.
20 . The system of claim 15 wherein the means for storing is a queue.
