By-Design Backdooring of Encryption System — Can We Trust Foreign Encryption Algorithms

Дата: 08.01.2020. Автор: CISO CLUB. Категории: Подкасты и видео по информационной безопасности

Backdooring encryption algorithms is considered as the best way to enforce cryptographic control. Until now, only implementation backdoors (at the protocol/implementation/management level) are generally considered. In this paper we propose to address the most critical issue of backdoors: mathematical backdoors or by-design backdoors, which are put directly at the mathematical design of the encryption algorithm. While the algorithm may be totally public, proving that there is a backdoor, identifying it and exploiting it, may be an intractable problem.
