Development of Modern Cryptography and Research on Quantum Cryptography
Masayuki Abe · NTT technical review · 2023
The foundation of modern cryptography developed in 1976 considered security by modeling adversaries as polynomial-time Turing machines.However, recent advances in developing a general-purpose quantum computer have made a significant impact on modern cryptography because it overturns the security model.NTT's research on cryptography aims to provide technologies to ensure the security of modern information systems and create applications when quantum computers become widespread.This article reviews the 40 years of cryptologic research at NTT and outlines our current efforts.
