STS/TECSEC has several technologies that provide a high degree of assurance that Multi-level security for Reprogrammable Electronic Devices is an achievable goal. The cornerstone of these technologies is a cryptographic key management system called Constructive Key Management (CKM). CKM is product which provides a unique method of generating cryptographic key and managing multiple algorithms. It has been accepted as a standard for Finance and Banking transactions by the American National Standards Institute (ANSI), has been implemented in an audio and imagery processing system under government contract and is available commercially in a file encryption, mail encryption and web site encryption product. Used with the second technology, a "Super" Smart Card having a 16-bit processor, 256 Kbytes of SRAM and 8 to 32 Mbytes of Flash Memory, a system of "split technology" can be achieved, protected by cryptography, allowing an individual to control only the authorized parameters of a reprogrammable device while at the same time providing multi-level security to the data flow. In addition, a third technology, Radio Frequency Resonant Signature will be used to authenticate and identify the SuperCards. This technology has been selected for use with US passports and Social Security card beginning in 1998 and is under consideration by the FAA for use on baggage tags in US airports. A fourth technology, presently being investigated for use on the SuperCard, would enable remote updates of the card, anywhere in the world. The "bringing together" of all these technologies plus the use of either a passphrase or biometrics to enhance authentication would provide a cryptographic process to configure the "Device" and also provide multi-level cryptographic security to the "data flow" created by the device.
