Thanks to David Wagner and Steve Schear, we've learned about the latest documents on cellular encryption which supercede the 1992 CAVE document, Appendix A to IS-54, which contained the CAVE algorithm. Here are the latest, followed by ordering information. TIA/EIA/IS-136.1-A -- TDMA Cellular/PCS - Radio Interface - Mobile Station - Base Station Compatibility - Digital Control Panel, October, 1996, 372 pp. $350.00. Addendum No. 1 to IS-136.1-A, November, 1996, 40 pp. Free. TIA/EIA/IS-136.2-A -- TDMA Cellular/PCS - Radio Interface - Mobile Station - Base Station Compatibility - Traffic Channels and FSK Control Channel, October, 1996, 378 pp. $310.00. TIA/EIA-627 -- 800 MHZ Cellular System, TDMA Radio Interface, Dual-Mode Mobile Station - Base Station Compatibility Standard, June, 1996, 258 pp. $120.00. These documents can be ordered from: Global Engineering Documents 15 Inverness Way East Englewood, Colorado 80112 Telephone: 1-800-854-7179 However, each of the documents lists the following related supplements which contain "sensitive information" and may be obtained by US/CA citizens from TIA by signing a Non-Disclosure Agreement and acceptance of export restrictions: Appendix A to IS-136. Appendix A to 627. Common Cryptographic Algorithms. Interface Specification for Common Cryptographic Algorithms. These controlled documents can be requested by calling Ms. Sharon Vargish at 1-703-907-7702, who will fax an NDA, and upon receipt of the completed form, will send the controlled documents at no cost. Here's the NDA: AGREEMENT ON CONTROL AND NONDISCLOSURE OF COMMON CRYPTOGRAPHIC ALGORITHMS REVISION A TO IS-54, IS-95, AND IS-136 [Note: 627 supercedes IS-54; IS-95 is for CDMA] "I, _________________________, an employee/consultant/affiliate (typed name) of __________________________, hereafter, "the company," (Company name) _____________________________ (Company address) _____________________________ and a United States or Canadian citizen, acknowledge and understand that the subject documents, to which I will have access contain information [which] is subject to export control under the International Traffic in Arms Regulations (ITAR) (Title 22, Code of Federal Regulations, Part 120-130).
