The first mention of Alice and Bob in the context of cryptography was in Rivest, Shamir, and Adleman's 1978 article "A method for obtaining digital signatures and public-key cryptosystems." [ 2 ] They wrote, "For our scenarios we suppose that A and B (also known as Alice and Bob) are two users of a public-key cryptosystem".
The problem of them agreeing on a random bit by exchanging messages over this channel, without relying on any trusted third party, is called the coin flipping problem in cryptography. [1] Quantum coin flipping uses the principles of quantum mechanics to encrypt messages for secure communication.
Cryptography is also a branch of engineering, but an unusual one since it deals with active, intelligent, and malevolent opposition; other kinds of engineering (e.g., civil or chemical engineering) need deal only with neutral natural forces. There is also active research examining the relationship between cryptographic problems and quantum physics.
Landrock was President of the International Association for Cryptologic Research from 1992 to 1995 [2] and General Chair at the Eurocrypt conference for cryptography research in 1990. [10] In 1996 he was one of the organizers of a research programme in Cryptography at the Newton Institute at University of Cambridge. [ 2 ]
Applications of cryptography include ATM cards, computer passwords, and electronic commerce. Modern cryptography is heavily based on mathematical theory and computer science practice; cryptographic algorithms are designed around computational hardness assumptions, making such algorithms hard to break in practice by any adversary. It is ...
The Theory of Cryptography Conference, often abbreviated TCC, is an annual conference for theoretical cryptography research. [6] It was first held in 2004 at MIT, and was also held at MIT in 2005, both times in February. TCC became an IACR-sponsored workshop in 2006.

The introductory text Winning Ways introduced a large number of games, but the following were used as motivating examples for the introductory theory: . Blue–Red Hackenbush - At the finite level, this partisan combinatorial game allows constructions of games whose values are dyadic rational numbers.
