Cryptography is Essential for Information Systems

860 Words2 Pages

Cryptography has a powerful tool used with computers and the computer network security. This paper will explore the threats, the can and cannot do the threats, system design, implementation, state of security, etc. All systems using cryptography for authentication and privacy with the strongest cryptographic can still be vulnerable with upstream and downstream threats. The secure session of the authentication will require the secure user to have authentication and secure computer authentication.

After reading Why Cryptography Is Harder than It Looks, Bruce Schneir explained it very well making it easy to understand why you need to use it.

Cryptography is the essential for the information systems, helping to provide accountability, accuracy, confidentiality, and fairness. Cryptography is designed to prevent fraudulent activity with the electronic commerce insuring the validity of all financial transactions. Also proving that is can help to protect the identity/anonymity while keeping the vandals from making changes to the Web page and prevent all industrial competitors from getting into the confidential documents the company has.

“As the Net and the Web move into more central positions in the life of the world, the functions that cryptography provides (including secrecy, integrity, and digital signatures) become more important, and cryptographic functions can be found in more places, doing more things.” (Morar, Chess, & Watson)

As the commerce and communication continue to move, forward with computer networks the use of cryptography will become more vital. “The cryptography now on the market does not provide the level of security it advertises. Most systems are not designed and implemented in concert with cryptographers, b...

The cryptography is designed with consideration of the users' needs, and integrated, so it can protect the systems, resources, and data. The hard part about cryptography is getting people to use and understand it; users do not know how to compare secure systems.
