Computer Security, Defines encryption and explain how it is used to protect transmission of information

1 Encryption is regularity of scrambling information in or so manner during transmission. In periods of struggle, the mathematical function of encoding becomes preponderating so those messages be non intercepted by the debate forces. There are a hail of various ways to protect data during transmission, such as Substitution (character for character replacement) in which mavin unit (usually character) of zero schoolbook (unintelligible textual matter or signals produced by means of an encryption system) is substituted for a corresponding unit of trim text (the intelligible text or signals that can be subscribe without using decryption), harmonize to the algorithm in intent and the particular key. The other system is Transposition (rearrangement characters) which is the encryption process in which units of the original plain text (usually individual characteristics) are merely moved nigh; they appear unchanged in the nada text for their relational locati on. Study Case ( edge of Shenandoah Valley) While twain encryption and enfranchisement method are providing some measures of security, the carrying out of security itself has totally a different approach. Before any(prenominal) methods chosen, the two most important factors in security implementations are having to be determined. The level of security inevitable and the cost involved, so the appropriate steps can be taken to operate a safe and secure environment.

In this case Bank of Shenandoah Valley is in type of line of products which a mellow level of security is required, therefore, I would pop the question the use of encryption method with a Byzantine algorithm involve d. Although an authentication method is a s! ecure method as well, is not as complex as encryption method of complex algorithm since it has been used in military during the war where a high levels of security are a must. During the war, the use of encryption becomes paramount so those messages are not intercepted by the opposing forces. This is...
