Symmetric ciphers

Symmetric ciphers

Symmetric ciphers use the same secret key to encrypt and decrypt, and their security is based on confidentiality of this key. We can divide symmetric ciphers into block symmetric ciphers and stream symmetric ciphers.

Cryptographic Systems

Cryptographic Systems

In SOS electronic, we got the opportunity to cooperate with prof. Ing. Dušan Levický, CSc., who published the book Applied Cryptography this year. We were so absorbed by some of the information in this book that we have decided to publish them in our set of articles. Are you courageous enough to embark on the secrets of encryption?
