Essay Boolean Logic
1555 Words  7 PagesBoolean Logic Many of our computer databases utilize boolean logic as the basis of querying the database. Boolean logic has a much older history than most computer users imagine. It is helpful to understand the background and theory behind this concept, because this theory is the foundation on which contemporary computer science and information technology has been built. George Boole was an English mathematician. Born in 1815, he had no formal higher education, but had a natural gift for mathematics…

A Brief History of Cryptography
1874 Words  8 PagesPeople wish to keep things like banking, medical, and political information from the eyes of unwelcome parties. This has created a need for cryptography. Cryptography is the science or study of the techniques of secret writing, especially code and cipher systems, and is used by everyone from the average citizen to the government and military. Cryptography was first used long before the invention of computers. One wellknown system was attributed to the reign of Julius Caesar (Klein ix). Another…

675 Words  3 PagesJpz777 05/15/2013 Order # A2096310 From the codes messages passed furtively throughout the courts of medieval Europe, to the infamous Enigma cipher machine which protected Nazi secrets in World War II, the concept of cryptography is nearly as old as the written word itself. Today, the field of information technology has developed to the point that even the most sophisticated encryption methods are vulnerable, and for those working as information security officers, shielding a company's invaluable…

A Closer Look At Cryptography Essay
2032 Words  9 PagesA Closer Look At Cryptography Ever since the earliest days of writing, people have had reasons to limit their information to a restricted group of people. Because of this, these people have had to develop ideas of making their information unable to be read by unwanted people. The general techniques used to hide the meaning of messages constitute the study known as cryptography. "Ciphers, in general fall into three major classifications: 1. Concealment Cipher, 2. Transposition Cipher, and 3.…
