Abstract
Methods and apparatus for performing encryption for data at rest at a port of a network device such as a switch are disclosed. Specifically, when data is received from a host during a write to a storage medium such as a disk, the data is encrypted by the port prior to transmitting the encrypted data to the storage medium. Similarly, when a host attempts to read data from the storage medium, the port of the network device receives the encrypted data from the storage medium, decrypts the data, and transmits the decrypted data to the host. In this manner, encryption and decryption of data at rest are supported by the port of the network device.
