NTIA Report TR-92-289Linking Protection in Federal Standard 1045 HF Radios Using the Data Encryption StandardDecember 1993Christopher Redding and William J. Pomper |
|
|
Abstract: A method of utilizing the Data Encryption Standard (DES) algorithm for linking protection in HF radios complying with Federal Standard 1045 is described. The unique DES encryption method, which permits a codebook type of encryption of 24-bit words, is explained in detail. Also discussed is the method used to integrate this encryption process with the Federal Standard 1045 automatic link establishment protocols. Processing speed requirements for the hardware and software used to implement this scheme are explained, and available DES devices that can support the described implementation are identified. |
