Error-Correcting Codes, not completely reliable. Even the best telecommunication systems connecting numerous information centres in various countries have some nonzero error rate. Error-correcting codes considered in this chapter were designed to resolve this problem. After a giving an example of a nonlinear code based on

Digital signatures are a special technique for achieving authentication. Nowadays cryptography has matured and it is addressing an ever increasing number of other goals like secr

We pay a special attention to orders of permutations and analysis of repeated actions. We briefly consider several topics, in general gro

This makes it possible to define “discrete logarithms”-special functions on finite fields that are difficult to compute, and widely used in cryptograp

If too few, they might all be lost or accidentally destroyed. Secret sharing schemes invented by Shamir ([21]) and Blakley (1979) address this problem and allow arbitrarily high levels of confidential
