CDISC-Gloss – A FIPS approved cryptographic algorithm for encrypting (enciphering) and decrypting (deciphering) binary coded information. Encrypting data converts it to an unintelligible form called cipher. Decrypting cipher converts the data back to its original form called plaintext. NOTE: Data that are considered sensitive by the responsible authority or data that represent a high value should be cryptographically protected if vulnerable to unauthorized disclosure or undetected modification during transmission or while in storage.
