• asymmetric cryptography — noun cryptography in which the key used in decryption is different from that used for encryption. One advantage of asymmetric cryptography is that you can exchange data without sharing the ability to read it …   Wiktionary

• data encryption — Process of disguising information as ciphertext, or data that will be unintelligible to an unauthorized person. Decryption is the process of converting ciphertext back into its original format, sometimes called plaintext (see cryptography).… …   Universalium

• Proxy re-encryption — schemes are cryptosystems which allow third parties (proxies) to alter a ciphertext which has been encrypted for one party, so that it may be decrypted by another. Examples of UseBob could designate a proxy to re encrypt one of his messages that… …   Wikipedia

• Plaintext-aware encryption — Plaintext awareness is a notion of security for public key encryption. A cryptosystem is plaintext aware if it is difficult for any efficient algorithm to come up with a valid ciphertext without being aware of the corresponding plaintext.From a… …   Wikipedia

• Probabilistic encryption — is the use of randomness in an encryption algorithm, so that when encrypting the same message several times it will, in general, yield different ciphertexts. The term probabilistic encryption is typically used in reference to public key… …   Wikipedia

• 40-bit encryption — refers to a key size of forty bits, or five bytes, for symmetric encryption; this represents a relatively low level of security. A forty bit length corresponds to a total of 2^{40} possible keys. Although this is a large number in human terms… …   Wikipedia

• One-way encryption — In cryptography, the term one way encryption has been used to refer to a number of different things: *One way function, a function difficult to invert. Note that encryption is, by definition, reversible. Hence, the term one way encryption is… …   Wikipedia
