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 predominant so those messages be non intercepted by the opposing forces. on that point atomic number 18 a annunciate of various ways to value data during transmission, such as Substitution (character for character replacement) in which one unit (usually character) of naught schoolbook (unintelligible textbook or signals produced through an encoding placement) is substituted for a corresponding unit of curry text (the intelligible text or signals that can be read without using decryption), combine to the algorithmic rule in implement and the specific key. The other system is Transposition (rearrangement characters) which is the encryption serve in which units of the original diaphanous text (usually individual characteristics) are simply moved most; they appear unchanged in the cipher text for their relational location. Study Case (Bank of Shenandoah valley) While both encryption and authentication regularity are providing some measures of certification, the implementation of security itself has totally a diametric approach. Before any methods chosen, the deuce most important factors in security implementations are having to be determined. The direct of security fatal and the cost involved, so the seize steps can be taken to ensure a safe and secure environment.

In this case Bank of Shenandoah Valley is in type of occupation of products which a tall level of security is required, therefore, I would soda water the question the use of encryption method with a intricate 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 army 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...
