Abstract
Methods and systems for implementing security operations in an input/output (I/O) device are disclosed. In an embodiment, an I/O (Input/Output) device involves an I/O port, a host bus configured to be connected to a host, a data processing pipeline within the I/O device coupled to the I/O port and to the host bus to process and forward data between the I/O port and the host bus, and a hardware security module (HSM) within the I/O device coupled to the host bus and to the data processing pipeline, the HSM comprising a crypto engine configured to encrypt and decrypt data of the data processing pipeline, and a secure key storage coupled to the crypto engine containing encryption keys for use in encrypting and decrypting packets, wherein the secure key storage contains keys that are encrypted by the HSM and that are accessible through the HSM.
