Attacks on Cryptographic Modules
 Daněček, Petr ; Zeman, Václav (advisor)
The conventional way of cryptanalysis is based on the cryptographic algorithms weak points examine. The attack model of conventional cryptanalysis covers mathematical description of the cryptographic algorithm used. This model is not with the relation to the physical model implementation and the real environment. Cryptographic algorithms currently used in the combination with strong cipher keys are almost unbreakable and the conventional cryptanalysis is ineffective. The new way of cryptanalysis employs the side channels. The model of cryptanalysis using side channels is enhanced with physical revelation of module performing the cryptographic operations. This dissertation thesis deals with cryptographic module description and studies influence of side channels to the security of this module.

Selected encyption methods
 MILICHOVSKÁ, Eva
The aim of this thesis is introduction into issues of classical cryptology from its beginnings in the antiquity to the half of the 20th century. Further, the division of basic ciphers on substitutional and transpositional ones is stated. Only the most important ciphers were chosen from the large number and demonstrations of decipherment were stated here, too. Then, the way of decipherment of Vigen?r´s "indecipherable" cipher is showed here.
