The process of unscrambling ciphertext and returning it to plaintext See also: Encryption
Decryption is the process of descrambling a scrambled or encrypted message Business transactions on the Web and e-mail messages are sometimes encrypted for security reasons
Decoding encrypted data to it's original form Dial Up: Connect to another computer by calling it over the telephone network Digital Certificate: In the common security standard for on-line transactions (SET), a Digital Certificate is issued by banks to each patron and each merchant to identify them as a valid transactor Domain: The Internet is divided into smaller sets known as domains, including com (business), gov (government), edu (educational) and others Domain Name: Allows you to reference Internet sites without knowing the true numerical address Download: The process of copying data file(s) from a remote computer to a local computer The opposite action is upload where a local file is copied to a server
Cryptography comprises encryption -- the process of making information unintelligible to the unauthorized reader -- and decryption -- reversing encryption to make the information readable once again Conventional cryptography uses a secret code or key to encrypt information The same secret key is used by the reciver to decrypt the information
Any procedure used in cryptography to convert ciphertext (encrypted data) into plaintext
The modification of encrypted data (with the help of a decryption key) to obtain the original data DK(encdat): Decryption of encdat with the help of the key K
the process reversing an encryption, i.e. the process which converts encrypted data into its original form
