Course Description

This course introduce historical techniques of encryption and their cryptanalysis. It cover topics such as public key cryptography (RSA, ElGamal systems), PKI (Public Key Infrastructure), and digital certificates management. The Data Encryption Standard (DES) and the Advanced Encryption Standard (AES) are also discussed. Participants will be able to identify digital signature schemes and key distribution. Secret sharing schemes and hash functions, Zero knowledge proofs, Integer and modular arithmetic are also among the topics discussed in the course. 

Course Objectives

  • Provide sufficient mathematical background to understand and analyze encryption/decryption algorithms
  • Prepare the participants for the challenging problems in the area of cybersecurity
  • Understand secure methods for data storage, data sharing and data transferring
  • Gain a deep knowledge of old and modern encryption techniques
  • Implement various types of public-key and private-key cryptosystems
