To roll over to the next key within the same key chain, configure a second key in the key chain, and a lifetime for the first key. MKA rolls over to the next configured valid pre-shared key in the key chain, when a valid key expires. Time zone of the key can be local or UTC. In the absence of a lifetime configuration, the default lifetime is unlimited. A key lifetime specifies the time period the key is valid. The PSK is used to generate the Key Encryption Key (KEK) and the integrity check value (ICV) Key (ICK).Ī MACsec key chain (MKA) can have multiple pre-shared keys (PSKs) each configured with a key ID and an optional lifetime. This key is shared between parties before it is used.

In symmetric cryptography, PSK means a key or a shared secret. Pre-shared keys (PSKs) are used to generate Connectivity Association Keys (CAKs). The MKA Protocol extends 802.1X to allow peer discovery with confirmation of mutual authentication and sharing of MACsec secret keys to protect data exchanged by the peers. The basic requirements of MKA are defined in 802.1X-2010. The MKA Protocol manages the encryption keys used by the underlying MACsec protocol. The switch also encrypts and adds an ICV to any frames sent over the secured port (the access point used to provide the secure MAC service to a client) using the current session key. If they are not identical, the frame is dropped. The switch compares that ICV to the ICV within the frame. When the switch receives frames from the client, it decrypts them and calculates the correct ICV by using session keys provided by MKA. MACsec frames are encrypted and protected with an integrity check value (ICV).

MKA MACsec supports both host facing links (links between network access devices and endpoint devices such as a PC or IP phone) and switch-to-switch links, beginning in Cisco IOS Release 15.2(5)E and Cisco IOS XE Release 3.9.0E.Ī switch using MACsec accepts either MACsec or non-MACsec frames, depending on the policy associated with the client. MKA and MACsec are implemented after successful authentication using the 802.1X Extensible Authentication Protocol (EAP) and EAP-Transport Layer Security (EAP-TLS) framework. The MACsec Key Agreement (MKA) Protocol provides the required session keys and manages the required encryption keys. MACse c, defined in 802.1AE, provides MAC-layer encryption over wired networks by using out-of-band methods for encryption keying. Understanding Media Access Control Security
