SYSTEM OF AND METHOD FOR SECURE FIRMWARE UPDATE AND LOADING OF CABLE MODEM

摘要

A system for and method of loading encrypted cable modem firmware from a non-volatile storage device maintained in a host upon power up. The host is coupled to the cable modem through an interface. The encrypted firmware is decrypted using one or more encryption keys maintained in the cable modem. The decrypted firmware is then stored in a volatile storage device maintained in the cable modem, and executed. Encrypted firmware updates may be received from an external source, such as cable operator head end, stored in a non-volatile storage device maintained in the host, decrypted in the cable modem, and executed.
