Title:
Quantum-Safe Protocols and Application in Data Security of Medical Records
Authors: Adrian-Daniel Stefan, Ionut-Petrisor Anghel, Emil Simion
Abstract:The use of traditional cryptography based on symmetric keys has been replaced with the revolutionary idea discovered by Diffie and Hellman in 1976 that fundamentally changed communication systems by ensuring a secure transmission of information over an insecure channel. Nowadays public key cryptography is frequently used for authentication in e-commerce, digital signatures and encrypted communication. Most of the public key cryptosystems used in practice are based on integer factorization (the famous RSA cryptosystem proposed by Rivest, Shamir and Adlemann), respectively on the discrete logarithm (in finite curves or elliptic curves). However these systems suffer from two potential drawbacks like efficiency because they must use large keys to maintain security and of course security breach with the advent of the quantum computer as a result of Peter Shor’s discovery in 1999 of the polynomial algorithm for solving problems such factorization of integers and discrete logarithm.
