The Data Inscription Standard Computer Science Essay
African Journal of Mathematics and Computer Science Research Vol. 3 10, pp. 267-269, The Data Encryption Standard DES Computer science as a career involves students as so-called computer scientists who study and apply scientific and practical approaches to computation. In this regard, a computer science student must be involved in systematic research into structures, expressions, and algorithms underlying data acquisition and representation. Encryption is the mechanism by which messages are changed into a form that cannot be read by the unauthorized user, known as ciphertext. . Only users with a secret key can access the text message. The message before it is sent without encryption is called plain text. Two mechanisms for encrypting messages are: Symmetric, Data Encryption Standard, The NBS Institute of Computer Science and Technology ICST started a project in the field of computer security, a subject that was still in its infancy at the time. One of the first objectives of the project was to develop a cryptographic algorithm standard that could be used to protect sensitive and valuable data. Read more7. Add the results for all characters together to generate a long int value. 8. Apply d SHA a,x. Where a: result of the above step. x, Random prime number. PUBLIC KEY, PRIVATE KEY amplifier DS generation 9. Obtain the public key QG x G, domain of the EC. x, random. Since private key D and public key Q have already been obtained, Perform,f,d,fully homomorphic encryption FHE, a type of privacy-preserving computation, provides a solution to this challenge. FHE enables calculations based on encrypted data, or ciphertext, to preserve data. Data Encryption Standard has a strong avalanche effect. B. Using this DES.
