  • Trusted personal computer system with identification
    Patent number: 5341422
    Abstract: This invention relates to personal computer systems and, more particularly, to such a system having security features enabling control over access to data retained in such a system. This invention contemplates protecting a personal computer system which has the capability of becoming a secure system from being placed into that condition by an attack on an unsecured machine. Additionally, in a network environment, it is important to maintaining network security that any given particular system be uniquely identified to the network, in order to guard against the substitution of an insecure "alternate" which would open the network to attack through an insecure system. This invention contemplates provision for such identification in a secure manner.
