"Provide, as a minimum, a two-stage mechanism for verifying all program components on demand via a communication port and protocol approved by the chairman. The mechanism must employ a hashing algorithm which produces a messages digest output of a least 128 bits and must be designed to accept a user selected authentication key or seed to be used as part of the mechanism (i.e. HMAC SHA-1). The first stage of this mechanism must allow for verification of all control components. The second stage must allow for the verification of all program components, including graphics and data components in a maximum of 20 minutes. The mechanism for extracting the verification information must be stored on a Conventional ROM Device."[1]
