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

1 Encryption is regularity of scrambling entropy in roughly manner during transmission. In periods of struggle, the mathematical function of encoding becomes paramount so those messages ar 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 unmatchable unit (usually character) of zero schoolbook (unintelligible schoolbook 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 take up without using decryption), harmonize to the algorithm in determination and the item 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 hardly moved nigh; they appear unchanged in the vigour text for their relational location. Study Case ( beach of Shenandoah Valley) While twain encryption and stylemark method are providing some measures of security, the execution of instrument of security itself has totally a different approach. Before both 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 regard a safe and secure environment.

In this case Bank of Shenandoah Valley is in type of line of products which a highschool level of security is required, therefore, I would pop the question the use of encryption method with a heterogeneous algorithm involved. Although an authentication method is a sec! ure 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...
