 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. 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… ipsec× 7 libsodium× 7 "The sodium crypto library". A cryptographic multi-language-library with support for many modern cryptographic primitives, that is a fork of the NaCl library. The library focuses on providing easy-to-… 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. 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 idea× 6 The International Data Encryption Algorithm (IDEA) is a block cipher developed in 1991 by James Massey and Xuejia Lai. file-format× 6 hardness-assumptions× 6 dual-ec-drgb× 6 short for Dual Elliptic Curve Deterministic Random Bit Generator; a pseudorandom number generator based on the elliptic curve discrete logarithm problem. education× 6 Questions related to the teaching and learning of cryptography. 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 $m$.… constants× 6 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. s-mime× 6 Secure/Multipurpose Internet Mail Extensions, or short S-MIME, is a standard for public key encryption and signing of MIME data. siphash× 6 A fast 64-bit PRF that can be used as a MAC 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'. siv× 5 a two-pass AEAD block cipher mode of operation described in RFC 5297. It can be used either for key-wrap (nonce-less deterministic authenticated encryption) or… universal-composability× 5 The framework of universal composability (UC) is a general-purpose model for the analysis of cryptographic protocols. 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 … camellia× 5 a 128-bit, symmetrical block cipher jointly developed by Mitsubishi and NTT of Japan. 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. negligible× 5 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 … proxy-re-encryption× 5 ocb× 5 The Offset CodeBook Mode, an authenticated encryption mode of operation for a block cipher. predicate-encryption× 4 an encryption paradigm which gives a master secret key owner fine-grained control over access to encrypted data. needham-schroeder× 4 Needham–Schroeder refers to both, a symmetric key or a public key authentication protocol. mixing-function× 4 to "scramble" or mix the internal state of a hash (or cipher) function. The input to the function is the current internal state and the output of the function bec… md4× 4 RFC 1320 — the MD4 message-digest algorithm — is a cryptographic hash function with a digest length is 128 bits, developed by Ronald Rivest in 1990. luby-rackoff× 4 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.
