Aim of the course

• Familiarize students with the provide basic knowledge about the fundamentals of cryptography and data safety.
• Familiarize students with the basic knowledge about applied cybersecurity (passwords, computer viruses and malware, firewalls, backups, SPAM, etc.).

Prerequisites

Principles of programming (but not obligatory).

 

Scope

Introduction: Fundamentals of cryptography and data safety, cryptosystems, basics of encryption and decryption, classic cryptography (transposition ciphers and substitution ciphers; Caesar cipher, Vigenère cipher, XOR, etc.). Implementation of the basic algorithms in programming languages.

Symmetric-key algorithms: Key management, block ciphers (DES, AES, Blowfish) and stream ciphers (RC4).

Optional: implementation in programming languages (C, C++, Java, Assembler, Pascal), hardware implementation (with programmable devices like FPGAs).

Asymmetric-key algorithms: Public and private keys, hash functions. Main protocols and cryptosystems (Diffie-Hellman, RSA, SHA, MD5, etc.).

Optional: Implementation in programming languages (C, C++, Assembler, Pascal). Hardware implementation (with programmable devices - FPGAs).

Digital signature: Fundamentals of digital signature, safety and authentication, smartcards.

Cryptanalysis: Main goals of cryptanalysis. Weakness of particular cryptosystems. Data safety. Debugging of computer applications and programs.

Data security and protection of applications: Fundamentals of data protection of programs and applications (based on MS Windows operation system). Processes management and debugging. Software debuggers and kernel mode debuggers.

Security in Web applications: Most popular attacks and protection methods (e.g. Cross-site scripting XSS, SQL-Injection).

Applied cybersecurity: protection of passwords, computer viruses and malware, firewalls, backups, SPAM.
