 remote-data-checking× 2 Remote data checking protocols allow a client that has stored data at an untrusted server to efficiently verify that the server possesses the original data without retrieving it. pkcs8× 2 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://… lucas× 2 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. memory-hard× 2 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… oblivious-ram× 2 a useful primitive that allows a client to hide its data access patterns from an untrusted server in storage outsourcing applications. 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 $A\in\mathcal{A}$ … 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… hashed-elgamal× 2 hermitian-curves× 2 desx× 2 an extension of DES that attempts to foil brute force attacks dpa× 2 error-propagation× 2 Property of cryptographic primitives to propagate errors. This usually means that an "error" in one block propagates into the following blocks, thereby flipping bits there or completely scrambling tho… blake2× 2 a cryptographic hash function. It was designed for the SHA-3 competition where it became a finalist, but wasn't chosen as SHA-3. blinding× 2 Technique mainly employed for factorization based cryptosystems to hide information. Usually blinding involves using a multiplicative homomorphic property of the cipher, it may be used to realize blin… cpu× 2 the most important hardware component of a computer system, since it contains the circuitry necessary to interpret and execute instructions. 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. arx Design philosophy for ciphers. ARX solely relies on additions, rotations and XORs to build ciphers and similar algorithms. This usually constructs ciphers that are highly resistant against side-channe… acoustic-cryptanalysis a type of side channel attack which exploits sounds emitted by computers or machines. falsifiable-assumption differential-privacy hard-core-predicate mulicast 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 … miracl md2 RFC 1319 — The MD2 Message-Digest Algorithm is a cryptographic hash function which is no longer considered secure. 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… logjam An attack on TLS and related protocols as of may 2015. This attack uses pre-computations to attack short prime diffie hellmann key exchange, primes with up to 1024 bits length are considered broken. I… 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. rc2 a symmetric-key block cipher designed by Ron Rivest in 1987. yubikey threefish A family of tweakable symmetric block-cipher algorithms with 256, 512 and 1024 bit block and key sizes. time-attack traitor-tracing Traitor tracing describes an ability of specific cryptographic schemes that helps trace the source of leaks.
