Course objectives
Lecture deals with the basic methods how to solve three key problems of the transmission of information. All three problems are of large practical importance and their solutions are based on elegant theoretical results. The first problem is how to make secure transmission of information through a noisy channel. Error-correcting codes are the main toolsfor doing that and they are dealt with in the first three lectures. Theory of error-coreecting codes is one of the most applied parts of algebra. Second problem is how to achieve that transmitted information does not get into un-authorized parties. Cryptography deals with this problem by developing various encryption and decryption methods. Related problems are that of the development of systems for secure digital signatures and cryptographic protocols that allow to perform several secure communication or cooperation tasks among various parties. Methods of classical and quantum cryptography will be introduced. Third problem is how to hide information to be transmitted in some other innoncently looking information. This task is of growing importance for a variety of reasons and a protection of intelectual properties is one of them. Basic techniques of steganography will be presented.
Syllabus
  • Coding theory and modern cryptography are rich on deep, elegant, interesting and practically very important ideas, methods, and systems. Main concepts of modern cryptography are closely connected with fundamental concepts of theoretical informatics. Current cryptohraphy and its methods and systems are of key importance for modern communication and information systems. Basic knowledge of coding methods and of modern cryptography are necessary for each graduate of informatics.
  • Lecture will be rich also on examples and experiences from a very rich and interesting history of cryptography.
  • Basic concepts of coding theory
  • Linear codes
  • Cyclic codes
  • Classical cryptography
  • Public-key cryptosystems
