Encryption algorithm

An encoding algorithm that takes random pairs of pixels and brightens the brighter pixel and dulls the duller pixel and encodes one bit of information in the contrast change. This algorithm creates a unique change, and that change indicates the absence or presence of a signature.

Advanced Encryption StandardAdvanced Encryption Standard, a new encryption standard, whose development and selection was sponsored by NIST, that will support key lengths of 128, 192, and 256 bits. FIPS approved cryptographic algorithm that is a symmetric block cipher using cryptographic key sizes of 128, 192, and 256 bits to encrypt and decrypt data in blocks of 128 bits. The encryption standard selected in October 2000 by the National Institute of Standards and Technology (NIST) that is based on the Rijndael cipher.

Algorithms applied to data that are designed to ensure confidentiality, integrity, authentication, and/or nonrepudiation. Art or science concerning the principles, means, and methods for rendering plain information unintelligible and for restoring encrypted information to intelligible form. The study of mathematical techniques related to aspects of information security such as confidentiality, data integrity, entity authentication, and data origin authentication. Cryptography is not the only means of providing information security services, but rather one set of techniques. The word itself comes from the Greek word kryptos, which means “hidden” or “covered. ” Cryptography is a way to hide writing but yet retain a way to uncover it again.

The number of binary digits, or bits, in an encryption algorithm’s key. Key length is sometimes used to measure the relative strength of the encryption algorithm.
