Abstract

A first network device may identify a MACsec session between the first network device and a second network device that utilizes a CAK, may determine, using a KDF and one or more KDF input parameters, an additional CAK, may encrypt the one or more KDF input parameters and/or KDF identification information that identifies the KDF and the one or more KDF input parameters to generate encrypted KDF input information, and may send, to the second network device, a first message that includes the encrypted KDF input information. The first network device may receive, from the second network device, based on sending the first message, a second message that includes a checksum value, may determine, based on the checksum value, that the second network device has determined the additional CAK, and may communicate, with the second network device, to cause the MACsec session to utilize the additional CAK.
