Trusted Processor: A Result of the Evolution of Information Barrier Technologies

Sandia National Laboratories (SNL) has previously developed a trusted processor (TP) for use with radiation identification technologies utilizing information barrier applications. Based on prior experience, including that gained via the evaluation of the SNL TP, VNIITF has been developing its own TP. The design of the VNIITF TP is associated with strict limitations being imposed by the sensitivity of the measurements being made. A TP design that recognizes the principles of security of sensitive data should also provide evidence for the presence of these functions. At the same time, the TP design should provide for simplicity and technological efficiency of any control operations. This paper will describe the following major technical principles, laid down into the Russian version of a TP during its design: • non-intrusiveness of TP • assurance of the reliability and authenticity of data in TP • transparency of TP • assurance of the authentication of TP
