data encryption key
81Television encryption — Television encryption, often referred to as scrambling , is encryption used to control access to pay television services, usually cable or satellite television services.HistoryPay television exists to make revenue from subscribers and sometimes… …
82Homomorphic encryption — is a form of encryption where one can perform a specific algebraic operation on the plaintext by performing a (possibly different) algebraic operation on the ciphertext. Depending on one s viewpoint, this can be seen as a positive or negative… …
83Hyper-encryption — is a form of encryption invented by Michael Rabin which uses a high bandwidth source of public random bits, together with a secret key that is shared by only the sender and recipient(s) of the message. It uses the assumptions of Ueli Maurer s… …
84Disk encryption hardware — To protect confidentiality of the data stored on a computer disk a computer security technique called disk encryption is used. This article discusses hardware which is used to implement the technique (for cryptographic aspects of the problem see… …
85public key encryption — An encryption scheme that uses two keys. In an e mail transaction, the public key encrypts the data, and a corresponding private key decrypts the data. Because the private key is never transmitted or publicized, the encryption scheme is… …
86Orders of magnitude (data) — Computer memory types can be ordered into a magnitude hierarchy: memory at the top is fastest to access but holds little data, while each lower type holds more, but is slower to access An order of magnitude is generally a factor of ten. A… …
87Media Key Block — The Media Key Block (MKB) is one of the keys that are included inside the copying protection system (DRM) AACS. This system is used to protect Blu ray and HD DVD formats from being copied. The system has been developed by big companies from the… …

89Client-side encryption — is the cryptographic technique of encrypting data before it is transmitted to a server in a computer network. Usually, encryption is performed with a key that is not known to the server. Consequently, the service provider is unable to decrypt the …
90Password-authenticated key agreement — In cryptography, a password authenticated key agreement method is an interactive method for two or more parties to establish cryptographic keys based on one or more party s knowledge of a password. Contents 1 Types 2 Brief history 3 See also …
