  • Non-disruptive authentication administration
    Patent number: 8340300
    Abstract: A configurable timer may be used for seamless authentication administration. A network administrator may set the timer value. Then the network administrator may begin to update the authentication configuration or key and the timer may begin to count down. While the timer counts down, the network device may still send outgoing packets using the old authentication configuration or key and may begin to authenticate incoming packets using both the old authentication configuration or key and the new authentication configuration or key. Once it expires, the network device may begin to send outgoing packets using just the new authentication configuration or key. The counter may then be reset and counted down again. Once the counter expires a second time, the new authentication configuration or key may be used for both incoming and outgoing packets. Two-timer implementations are also possible.
