Abstract

Since the Data Encryption Algorithm DES was accepted as a Standard in 1977 [4], few new conventional cryptosystems have been proposed in the open literature [5]. However DES is not necessarily the most suitable encryption procedure for all applications. For example two people desiring to set up a private secure communication channel may not want to use a standardized encryption algorithm; or communicating parties may want to choose from a set of encryption algorithms, trading off speed against security. In this paper we propose two new conventional cryptosystems that are
  • adaptable (parameters can be chosen to increase or decrease execution time and level of security),

  • efficient (the algorithms are fast, even when implemented in a high level computer language), - easy to program (both algorithm can be written in less than 100 lines) and

  • conceptually simple.

Keywords

These keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.
