SAVREMENI KRIPTOGRAFSKI PROTOKOLI

Abstract

In this paper we describe the basics of cryptography, how to protect the confidentiality 
of information. Symmetric and asymmetric algorithms that provide security by using a 
secret key are defined. 
The basics of security are defined, the possibility of authentication of messages, 
authorization, validation, intransigence, anonymity, etc. An important security feature is 
that the data is readable only to those to whom it is intended, while those for whom it is 
not intended will not be legible and can not be used. 
Finally, basic cryptographic protocols are provided that provide protection on all layers 
of the OSI reference model.
