Post-Quantum Crystography: A combination of Post-Quantum Cryptography and Steganography
This paper proposes a new Crystographic System that combines Post Quantum Cryptography with Steganography to ensure that security of communication is maintained both in Classical Computing era as well as Post-Quantum Computing era.
Abstract
Crystography is the combination of Cryptography and Steganography for enhancing the security of communications over enterprise networks. Most existing Crystographic systems are based on Public key Cryptographic schemes like RSA and Elliptic Curve Cryptography (ECC), whose security depends on the difficulty of solving Integer Factorisation Problem (IFP) and Discrete Logarithm problem (DLP) respectively. However, techniques for solving IFP and DLP problems, improves continually. Therefore, the existence of Quantum Computers in the range of 1000 bits would be a real world threat to systems based on those problems. This paper thus propose a new Crystographic System that combines Post Quantum Cryptography with Steganography to ensure that security of communication is maintained both in Classical Computing era as well as Post-Quantum Computing era.
