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

1 Encryption is regularity of scrambling data in some manner during transmission. In periods of struggle, the mathematical function of encoding becomes prevailing so those messages argon non intercepted by the opposing forces. thither be a announce of various ways to nourish data during transmission, such as Substitution (character for character replacement) in which one unit (usually character) of zipper schoolbook (unintelligible schoolbook or signals produced through an encoding strategy) is substituted for a corresponding unit of make out text (the intelligible text or signals that can be read without using decryption), chord to the algorithmic program in physical exercise and the specific key. The other system is Transposition (rearrangement characters) which is the encryption multitude operation in which units of the original cable system of business text (usually individual characteristics) be simply moved just about; they appear unchanged in the cipher text for their comparative location. Study Case (Bank of Shenandoah vale) While both encryption and authentication regularity are providing some measures of protection, the implementation of security itself has totally a different approach. Before any modes chosen, the devil most important factors in security implementations are having to be determined. The level of security indispensable and the cost involved, so the assign steps can be taken to ensure a safe and secure environment.

In this case Bank of Shenandoah Valley is in type of line of products which a tall level of security is required, therefore, I would issue the question the use of encryption method with a confused algorithm involved. Although an authentication method is a secure method as well, is non 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...
