Computer Science and Technology: Maintenance Testing for the Data Encryption Standard

摘要

The publication describes the design of maintenance tests for the Federal Information Processing Data Encryption Standard (DES). The test consists of an iterative procedure that completely tests the operation of DES devices by using a small program and minimum data. The tests are designed to be independent of implementation and to be fast enough to test devices during actual operation. The tests are defined as four stopping points in a general testing process, and satisfy four testing requirements depending on the thoroughness of testing desired.
