source: ISO18033-4, 2005
The act or process of translating a message into hidden form using a secret formula, or algorithm, with the goal of ensuring message confidentiality. Encrypt is synonymous with the term encipher.
source: Champlain, Auditing Information Systems:2003
A technique for scrambling data to prevent unauthorized users from reading or tampering with that data. The data can include messages, files, folders, or disks, and only those with a password or key can decrypt and use the data.
source: D. Schweitzer, 2003, Incident Response: Computer Forensics Toolkit
Process of converting information into an unintelligible form except to holders of a specific cryptographic key. Use of encryption protects information between the encryption process and the decryption process (the inverse of encryption) against unauthorized disclosure.
