To master the basics of the theory and technology of high reliability and confidentiality in information and communications,
and to provide a foundation for deeper study as an engineer.
This is a introductory course for a basic cryptography and coding theory.
In constructing the system of information or communication, any information must be represented by a suitable code.
Such a code might be a cryptographic code for serucity, an source coding for an efficient information compression, or a channel coding for a fast and reliable communication.
The first part of this lecture presents a basis of the theory of cryptography.
Starting from an elementary methods of cryptography, students will learn both the symmetric-key crptography and the public key crpytography,
including ONE-TIME-PAD, RSA, DES, etc.
The second part of this lecture presents a basis of the communication channel coding theory.
In particular, students will learn an error correcting code focusing on block code and convolution code.
Exercises will be conducted to aid practical understanding of the lectures.
