Encryption process

Encryption is the formal name for the scrambling process. We take data in their normal unscrambled state called clear text and transform them so that they are unintelligible to the outside observer the transformed data are called enciphered text. Using encryption security professionals can virtually nullify the value of an interception and the possibility of effective modification or fabrication.

 Encryption clearly addresses the need for confidentiality of data. Additionally it can be used to ensure integrity; data that cannot be read generally also cannot easily be changed in a meaningful manner. Although encryption is an important tool in any computer security tool kit, we should not overrate its importance. Encryption does not solve all computer security problems and other tools must complement its use.
