 secure-index× 2 mixing-function× 2 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… miyaguchi-preneel× 2 The Miyaguchi-Preneel scheme, based on a one-way compression function, was proposed around 1989 by Preneel, and independently by Miyaguchi.Ohta, and Iwata. monotone-access-structure× 2 Let $\Omega$ be a set of entities. An *access structure* $\mathcal{A}$ is a collection of nonempty subsets of the power set $P(\mathcal{A})$. This structure is called *monotone*, if $A\in\mathcal{A}$ … negligible× 2 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 … key-escrow× 2 key-rotation× 2 Key rotation refers to a schedule or process for changing the key material. luby-rackoff× 2 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… md4× 2 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. hashed-elgamal× 2 hermitian-curves× 2 hybrid× 2 Something of mixed origin. In cryptography, typically a cipher system containing both public key and secret key component ciphers, where the public key system is used only to transport the key for the… double-encryption× 2 the process of encrypting a message multiple times, either using the same or a different algorithm. embedded× 2 a computer system with a dedicated function within a larger mechanical or electrical system, often with real-time computing constraints. cpu× 2 the most important hardware component of a computer system, since it contains the circuitry necessary to interpret and execute instructions. congruence× 2 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 $m$.… cramer-shoup Cramer-Shoup asymmetric encryption (an extension of ElGamal) crl one of two common methods when using a public key infrastructure for maintaining access to servers in a network. cryptoapi The Cryptographic Application Programming Interface is an application programming interface included with Microsoft Windows operating systems that provides services to enable developers to secure Wind… acoustic-cryptanalysis a type of side channel attack which exploits sounds emitted by computers or machines. access-control 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. ephemeral short-lived, like (for example) an ephemeral key, which is a key that only exists within the lifetime of a communication session. ecies Elliptic Curve Integrated Encryption Scheme (ECIES) is a public key encryption system proposed by Victor Shoup in 2001. homomorphic-signatures A homomorphic signature scheme (also malleable signature scheme) is a digital signature scheme that allows computations on signed data (without access to the secret signing key) while preserving the… hamming a family of binary, linear error-correcting codes that are used to detect and correct data transmission errors. Hamming codes are able detect up to two simultaneous bit errors and ca… md2 RFC 1319 — The MD2 Message-Digest Algorithm is a cryptographic hash function which is no longer considered secure. meta-cryptography mars a 128-bit block cipher with variable key size of between 128 and 448 bits. It has a heterogeneous structure: several rounds of a cryptographic core are “jacketed” by un-keyed mixing rounds, to… niederreiter a variation of the McEliece Cryptosystem and is equivalent to McEliece from a security point of view, but encryption using Niederreiter is about ten times faster than … oblivious-ram a useful primitive that allows a client to hide its data access patterns from an untrusted server in storage outsourcing applications. skipjack a 64-bit block cipher developed by the U.S. National Security Agency (NSA). sha-3-competition SHA-3 Competition (2007-2012) was a competition initiated by NIST as a call for a new cryptographic hash algorithm for standardization purposes. rc6 a 128-bit block cipher, formerly an AES candidate, that makes heavy use of data-dependent rotations. rsap a variant of RSA, meant to increase the RSA public modulus size while keeping computation cost moderate. pkcs8 Public-Key Cryptography Standard, number 8, describes the Private-Key Information Syntax Standard which is used to carry (encrypted or unencrypted) private certificate keypairs. See [RFC 5208](http://… suite-b a set of cryptographic algorithms promulgated by the National Security Agency as part of its Cryptographic Modernization Program.
