  • Patent number: 10243928
    Abstract: Various techniques that allow group members to detect the use of stale encryption policy by other group members are disclosed. One method involves receiving a message from a first group member via a network. The message is received by a second group member. The method then detects that the first group member is not using a most recent policy update supplied by a key server, in response to information in the message. In response, a notification message can be sent from the second group member. The notification message indicates that at least one group member is not using the most recently policy update. The notification message can be sent to the key server or towards the first group member.

  • Patent number: 8656170
    Abstract: Techniques are provided for determining freshness of control messages in a network. At a first device that is to enter into a secure communication session with a second device, timestamp information and time window size information are sent to the second device in a control message during a first exchange between a first device and a second device. At the first device, timestamp information and time window size information are obtained from a control message received from the second device by the first device during the first exchange. At the first device, the freshness of a control message is tested based on the timestamp information of the control message during a second exchange and the time window size information received from the second device during the first exchange.
