 mental-poker× 7 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. ipsec× 7 index-of-coincidence× 7 a measure of the relative frequency of letters in a cipher text sample, which facilitates cryptanalysis of poly-alphabetic ciphers by allowing determination of the per… resources× 7 material that can be referenced for further information on cryptography. ripemd× 7 The RACE Integrity Primitives Evaluation Message Digest (RIPEMD) is a family of cryptographic hash functions. simon× 7 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. secure-channel× 7 timed-release× 7 Time-lock puzzles and other cryptographic schemes intended to ensure that a message cannot be read until a certain time has passed. searchable-encryption× 6 a subfield of cryptography which constructs and analyzes cryptosystems that preserve the ability to 'search' over encrypted data, for some definition of 'search'. schnorr-identification× 6 The Schnorr Identification Protocol relies upon the security of the Discrete Logarithm Problem. Schnorr's protocol was introduced after, and is comparable to, the identification protocol of Fiat and S… siphash× 6 A fast 64-bit PRF that can be used as a MAC smartcard× 6 universal-composability× 6 The framework of universal composability (UC) is a general-purpose model for the analysis of cryptographic protocols. idea× 6 The International Data Encryption Algorithm (IDEA) is a block cipher developed in 1991 by James Massey and Xuejia Lai. literature× 6 Literature describes everything that has been written and/or visualized (here: in relation cryptography), which ranges from papers to books, and from publications to presentations. key-wrap× 6 negligible× 6 so unimportant, that it isn't worth considering. For example, if a flaw in a cryptographic algorithm is considered to be negligible, it is insignificant to both the … memory-hard× 6 a property that, if proven to be possesed, makes an algorithm "immune" to time-memory tradeoffs, by "punishing" memory reductions. Usually algorithms possesing this property can't e… garbled-circuits× 6 used in Secure Multiparty Computation dual-ec-drbg× 6 short for Dual Elliptic Curve Deterministic Random Bit Generator; a pseudorandom number generator based on the elliptic curve discrete logarithm problem. copy-protection× 6 Copy protection or content protection covers various mechanism, such as DRM and software license keys, used to restrict the unauthorized copying or use of software or digital media. congruence× 6 If two numbers $b$ and $c$ have the property that their difference $b-c$ is integrally divisible by a number $m$ (i.e., $(b-c)/m$ is an integer), then $b$ and $c$ are said to be "congruent modulo $m$.… camellia× 5 a 128-bit, symmetrical block cipher jointly developed by Mitsubishi and NTT of Japan. certificateless-crypto× 5 a variant of ID-based cryptography intended to prevent the key escrow problem. Only a partial private key is generated by the key generation center (KGC) and the other … bijection× 5 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 … access-control× 5 a possible goal of cryptography, where the idea is to restrict access to documents, equipment, locations, or keys to individuals who are authorized such access. ecies× 5 Elliptic Curve Integrated Encryption Scheme (ECIES) is a public key encryption system proposed by Victor Shoup in 2001. elliptic-curve-generation× 5 education× 5 Questions related to the teaching and learning of cryptography. luby-rackoff× 5 a Feistel cipher where in each round the nonlinear function used is assumed to be chosen uniformly at random from the set of all such functions. These ciphers are mainly of th… knapsack× 5 the problem of determining which numbers from a given collection of numbers have been added together to yield a specific sum: used in cryptography to encipher (and sometimes decipher) mess… key-recovery× 5 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. probabilistic-encryption× 5 the use of randomness in an encryption algorithm, so that when encrypting the same message several times it will, in general, yield different ciphertexts. proxy-re-encryption× 5 pir× 5 A PIR (Private Information Retrieval) protocol allows a user to retrieve an item from a server in possession of a database without revealing which item is retrieved. ocb× 5 The Offset CodeBook Mode, an authenticated encryption mode of operation for a block cipher.
