Abstract
Automatic key rolling for link encryption is described. In accordance with the described techniques, data packets are encrypted at a first endpoint of a communication link using a first data encryption key. The encrypted data packets are communicated over the communication link to a second endpoint. A key rolling event that is known by both the first endpoint and the second endpoint is detected at the first endpoint. Responsive to detecting the key rolling event, the first data encryption key is rolled to a second data encryption key for encrypting data packets communicated over the communication link. In one or more implementations, the second endpoint is also configured to roll from the first data encryption key to the second data encryption key responsive to the key rolling event in order to decrypt data packets encrypted with the second data encryption key which are received from the first endpoint.
