WebbIn cryptography, a cipher (or cypher) is an algorithm for performing encryption or decryption—a series of well-defined steps that can be followed as a procedure. An alternative, less common term is encipherment.To encipher or encode is to convert information into cipher or code. In common parlance, "cipher" is synonymous with … WebbQuantum cryptography was first proposed by Stephen Weisner in his work "Conjugate Coding" in the early 1970s. The proposal was published in 1983 in Sigact News, and by that time two scientists Bennet and Brassard, who were familiar with Weisner's ideas, were ready to publish their own ideas.
