• Strong cryptography — or cryptographically strong are general terms applied cryptographic systems or components that are considered highly resistant to cryptanalysis. Demonstrating the resistance of any cryptographic scheme to attack is a complex matter, requiring… …   Wikipedia

• Strong secrecy — is a term used in cryptography. Bruno Blanchet provides the following definition:: Strong secrecy means that an adversary cannot see any difference when the value of the secret changes [Blanchet, B. (2004) Automatic proof of strong secrecy for… …   Wikipedia

• Transparent end-to-end encryption for the internets — (IPETEE) is a proposal for a network level encryption method which would effectively encrypt all internet communication. The encryption would be handled by software on the client and server machines, and would negotiate the encryption behind the… …   Wikipedia

• Deterministic encryption — A deterministic encryption scheme (as opposed to a probabilistic encryption scheme) is a cryptosystem which always produces the same ciphertext for a given plaintext and key, even over separate executions of the encryption algorithm. Examples of… …   Wikipedia

• Disk encryption — uses disk encryption software or hardware to encrypt every bit of data that goes on a disk or disk volume. Disk encryption prevents unauthorized access to data storage. The term full disk encryption (or whole disk encryption) is often used to… …   Wikipedia

• Disk encryption theory — Disk encryption is a special case of data at rest protection when the storage media is a sector addressable device (e.g., a hard disk). This article presents cryptographic aspects of the problem. For discussion of different software packages and… …   Wikipedia

• Disk encryption software — To protect confidentiality of the data stored on a computer disk a computer security technique called disk encryption is used. This article discusses software that is used to implement the technique (for cryptographic aspects of the problem see… …   Wikipedia

• Format-preserving encryption — In cryptography, format preserving encryption (FPE) refers to encrypting in such a way that the output (the ciphertext) is in the same format as the input (the plaintext). The meaning of format varies. Typically only finite domains are discussed …   Wikipedia

• Opportunistic encryption — (OE) refers to any system that, when connecting to another system, attempts to encrypt the communications channel otherwise falling back to unencrypted communications. This method requires no pre arrangement between the two systems. Opportunistic …   Wikipedia

• Cryptographically strong — This term cryptographically strong is often used to describe an encryption algorithm, and implies, in comparison to some other algorithm (which is thus cryptographically weak), greater resistance to attack. But it can also be used to describe… …   Wikipedia
