 dual-ec-drgb× 4 short for Dual Elliptic Curve Deterministic Random Bit Generator; a pseudorandom number generator based on the elliptic curve discrete logarithm problem. fortuna× 4 a family of cryptographically secure PRNGs; devised by Bruce Schneier and Niels Ferguson, who published it in 2003. secure-channel× 4 resources× 4 material that can be referenced for further information on cryptography. proxy-re-encryption× 4 license-key× 4 a typically short alphanumeric code used as a software copy-protection mechanism, by requiring a user to enter a valid key before they can use the software. mental-poker× 4 the common description for a set of cryptographic problems related to playing a fair game over a distance without the need for any trusted third party. onion-routing× 4 A method for anonymous communications over a wide area network such as the Internet. timed-release× 4 Time-lock puzzles and other cryptographic schemes intended to ensure that a message cannot be read until a certain time has passed. trapdoor× 4 a function that is easy to perform one way, but has a secret that is required to perform the inverse calculation efficiently. tweakable-cipher× 3 a family of permutations where the key selects a particular permutation from that family. With a tweakable blockcipher both key and tweak are used to select a permutation. So tweak a… u-prove× 3 a Crypto SDK was developed by Microsoft to support experimentation with the foundational features of the U-Prove technology. It is made available under the Apache 2.0 open-source license, w… xts× 3 a block cipher mode of operation, which is most commonly used when random accessible data (like a hard disk or RAM) is to be encoded. oaep× 3 a padding scheme which has been standardized in [PKCS #1v29](http://www.emc.com/collateral/white-papers/h11300-pkcs-1v2-2-rsa-cryptography-standard-wp.pdf) and… pkcs11× 3 Public-Key Cryptography Standard number 11 is one of the family of standards called Public-Key Cryptography Standards (PKCS). montgomery× 3 key-wrap× 3 rabin-cryptosystem× 3 A public-key cryptosystem based on squaring modulo the product of two primes, introduced in 1979 by Michael O. Rabin and proven to have security reducible to the hardness of integer factorization. predicate-encryption× 3 an encryption paradigm which gives a master secret key owner fine-grained control over access to encrypted data. pseudo-random-permutation× 3 a function that cannot be distinguished (with practical effort) from a permutation selected at random with uniform probability from the family of all permutations … ripemd× 3 The RACE Integrity Primitives Evaluation Message Digest (RIPEMD) is a family of cryptographic hash functions. simon× 3 A family of lightweight symmetric block-ciphers designed for good performance in hardware with block sizes ranging from 32 to 128 bits and key sizes ranging from 64 to 256 bits. skein× 3 a cryptographic hash function. It was designed for the SHA-3 competition where it became a finalist, but wasn't chosen as SHA-3. key-distribution× 3 key-recovery× 3 A means of recovering cryptographic keys when the usual means for obtaining them is unavailable.; the ability to uncover the secret key to a cryptographic message. ipsec× 3 deterministic-encryption× 3 a cryptosystem which always produces the same ciphertext for a given plaintext and key, even over separate executions of the encryption algorithm. data-privacy× 3 Data privacy refers to (cryptographic) methods to prevent the disclosure of sensitive (identifying) information of persons. decryption-oracle× 3 biclique-attack× 3 bijection× 3 a function $f$ from a set $X$ to a set $Y$ with the property that, for every $y$ in $Y$, there is exactly one $x$ in $X$ such that $f(x) = y$. It follows from … cfb× 3 an encryption mode, that builds a self-synchronizing stream-cipher from a block-cipher. asn.1× 3 a language that defines the way data is sent across dissimilar communication systems. alternating-step× 2 blocksize× 2 a sequence of bytes or bits, having a fixed length (the block-size). constants× 2 Fixed, more or less arbitrary parameter values that appear in the definitions of cryptographic schemes, such as fixed initialization vectors for hash functions or S-box tables for block ciphers.
