# Mathematical Theory Applied in Coding and Cryptography

Coding and cryptography are essential subjects in the fields of information security and communication, and they have been applied widely in information technology for several decades. Coding and cryptography are closely related to many mathematical subjects, such as, algebra, number theory and combinatorics. An in-depth study of coding and cryptography needs profound methodology in such mathematical fields.

Topics of this workshop include but are not limited to:

* Open problems and conjectures in coding theory;

* Optimal error-correcting codes, sequences and cryptographic functions designed
by using the tools of the theories of finite field, combinational design and exponential sum;

* Links between cryptographic functions and mathematical structures such as semi-field, permutation polynomial, difference set and hyper-elliptic curve.

* Algebraic geometry codes, computational number theory and the related problems
