Abstract

Official abstract text for this publication.

A method of implementing security in a wireless communication device ( 108 ) comprises receiving ( 300 ), at the device ( 108 ), a security mode command for activating a security mode in the device and storing a sequence number of the received security mode command. A security mode complete or failure message is sent ( 302 ) based on whether a security mode is activated in the device. An acknowledgement of the security mode complete or failure message is received ( 304 ) and a timestamp of the acknowledgement is stored. On receiving a PDU, sequence numbers and timestamps of segments of the received PDU are compared ( 306 ) with the stored sequence number and timestamp of the acknowledgement. The received PDU segments are managed ( 308 ) in response to the comparisons, and the sending of the security mode complete or security mode failure message. A wireless communication device is also disclosed.
