  • Two factor authentication of ICR transport and payload for interchassis redundancy
    Patent number: 9319222
    Abstract: Exemplary methods for performing authentication by a first network device of an inter-chassis redundancy (ICR) system, the ICR system comprising the first network device communicatively coupled to a second network device of the ICR system, includes in response to determining to transmit an ICR message to the second network device, generating the ICR message by generating a first and second authentication digest. In one embodiment, the methods include encrypting a payload of the ICR message, and transmitting the ICR message that includes the first and second authentication digest to the second network device. In another aspect of the invention, the methods include receiving an ICR message from the second network device and performing a first level authentication of the received ICR message. The methods further include in response to determining the first level authentication is successful, performing a second level authentication of the received ICR message.
