Application: Automatic generation and update of connectivity association keys for media access control security protocol (Patent ID: US20230421360A1)
The patent filed by Juniper Networks Inc. describes a method and system for enhancing security in a network by allowing a first network device to determine an additional connectivity association key (CAK) for a Media Access Control Security (MACsec) session with a second network device. This is achieved by using a key derivation function (KDF) and encrypting the KDF input parameters to generate encrypted information, which is then sent to the second network device. The second network device confirms the determination of the additional CAK by sending a message with a checksum value, leading to the utilization of the additional CAK in the MACsec session.
The method involves the encryption of KDF input information using a secure association key (SAK) or a key encryption key (KEK) associated with the MACsec session. The communication between the first and second network devices is facilitated through MACsec key agreement protocol data units (MKPDUs) containing encrypted KDF input information and checksum values. The second network device decrypts the information received to determine the additional CAK, ensuring secure communication between the devices. This patent aims to improve the security and efficiency of MACsec sessions in network environments by enabling the dynamic generation and utilization of additional CAKs.
