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

1 Encryption is regularity of scrambling selective information in each(prenominal) manner during transmission. In periods of struggle, the mathematical function of encryption becomes paramount so those messages ar non intercepted by the opponent forces. There be a hail of various ways to protect data during transmission, such as Substitution (character for character replacement) in which matchless unit (usually character) of zero schoolbook (unintelligible text edition or signals produced by dint of an encryption system) is substituted for a corresponding unit of trim text (the intelligible text or signals that can be guide without using decryption), harmonize to the algorithm in work and the particularized 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 just now moved nigh; they appear unchanged in the grave text for their relational location. Study Case ( camber of Shenandoah Valley) While both(prenominal) encryption and stylemark method are providing some measures of security, the slaying of security itself has totally a different approach. Before any 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 agree a safe and secure environment.

In this case Bank of Shenandoah Valley is in type of line of products which a senior high school level of security is required, therefore, I would pop the questio n the use of encryption method with a knott! y algorithm involved. Although an authentication method is a secure 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...
