We refer to a commutative ring with 1 as a crw1. proving that the RSA encryption/decryption procedure works - when Bob decrypts the cipher \(C\) he obtains Alice's message \(M\).The remarkable feature of RSA cryptography is that Alice need only send the remainder \(C\) to Bob, and yet Bob is able to reconstruct Alice's entire message, as can be mathematically proven in just a few lines!. A ring Ais an integral domain if A6= 0 and for every a;b2A ab= 0 implies a= 0 or b= 0. Ring Theory A ring is a set equipped with two operations (usually referred to as addition and multiplication) that satisfy certain properties: there are additive and multiplicative identities and additive inverses, addition is commutative, and the operations are associative and distributive. The result, An introduction to homological algebra, took over five years to write. Examples Look at those above to pick out the crw1's. There is a natural bijection between A Aand A2. Introduction to Ring Theory. By the previous lemma this is equivalent to A=I is a field. I is a maximal ideal of Aiff A=I is a field. It starts with the definition of a ring (!)
