Cryptography is derived from the Greek words kryptos meaning “hidden” and graphien‚ meaning “to write/study”. The process of making and using codes to secure the transmission of information is called cryptography. Before modern era cryptography was synonymous to encryption but today cryptography is heavily based on mathematical theory and computer science practice. Cryptography today deals with the ways to transfer information in such a manner that no one beside the recipients can read what was actually

that as more people start to use wireless fidelity (Wi-Fi) networks‚ improvements to the wireless technology are needed to ensure reliable and secure services. An increase in popularity of Wi-Fi has come at the cost of creating difficult problems for designers of the technology. However‚ Hills notes that there has been "substantial progress" towards solving many of these problems. Hills covers some of the developments in wireless local area network (LAN) technology since he and his team built the
