Random numbers are very important in many fields of computer science, especially in cryptography. One of the most important usage of pseudorandom number generators (PRNG) are key generation methods for cryptographic purposes. In PKI systems prime number generation is a vital process to make protocols secure. This course explains through practical and real examples how to identify and hide backdoors in asymmetric cryptographic protocols using modified random number generators. This class is focusing on practical examples and real life case studies. During the course we will analyze and implement fully undetectable and indistinguishable backdoors in common applications such as SSH, HTTPS, PGP and VPN.

Why You Should Take This Course

This class is meant for security researchers with passion for Cryptography, Number theory and Penetration testing.

Who Should Attend

– Advanced CTF players – Cryptography Enthusiasts – Penetration testers – Ethical hackers – Bug hunters – Security engineers / consultants
