Modular authentication systems
Authentication system are required in situations where it is not necessary to protect the contents of the information but to verify the transfer of the information. The Modular Video Authentication System (MVAS) has been developed by Sandia National Laboratories to provide authentication of video signals in already-wired systems. The video authentication technique uses similar microprocessor circuitry at the transmission point, and at the receiving point, to select sample points from the video images for comparison. If a significantly different image was substituted, the comparison would fail at a number of points and the video image would not be authenticated. A similar system has been developed by Sandia for authenticating digital data transmissions. This system is used to determine whether any data alternation or substitution has occurred between the point of the data transmission and the point of the data reception. As with the MVAS, authentication equipment is required at both the transmission and receiving locations for the system operation. This paper describes both the video authentication system and the digital data authentication system, how authentication is accomplished, and how the systems interface with existing hardware. 3 figs.
