 monotone-access-structure× 4 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 $A\in\mathcal{A}$ … universal-re-encryption× 4 xsalsa20× 4 a variant of the Salsa20 cipher with a longer nonce. s-mime× 4 Secure/Multipurpose Internet Mail Extensions, or short S-MIME, is a standard for public key encryption and signing of MIME data. remote-data-checking× 4 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. threefish× 3 A family of tweakable symmetric block-cipher algorithms with 256, 512 and 1024 bit block and key sizes. tea× 3 a block cipher by David Wheeler and Roger Needham of the Cambridge Computer Laboratory; notable for its simplicity of description and implementation. 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… traffic-analysis× 3 the process of intercepting and examining messages in order to deduce information from patterns in communication. Within cryptography this definition is restricted to deduce inform… mixnets× 3 routing protocols that create hard-to-trace communications by using a chain of proxy servers known as mixes which take in messages from multiple senders, shuffle them, and send them b… keyak× 3 kbkdf× 3 a key derivation function ([tag:kdf]) that uses a key in the computation. predicate-encryption× 3 an encryption paradigm which gives a master secret key owner fine-grained control over access to encrypted data. p1363× 3 a set of public key cryptography standards provided by the IEEE. onion-routing× 3 A method for anonymous communications over a wide area network such as the Internet. biclique-attack× 3 cpu× 3 the most important hardware component of a computer system, since it contains the circuitry necessary to interpret and execute instructions. cramer-shoup× 3 Cramer-Shoup asymmetric encryption (an extension of ElGamal) cryptoapi× 3 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… desx× 3 an extension of DES that attempts to foil brute force attacks hard-core-predicate× 3 feal× 3 a block cipher designed by NTT. It is known to be insecure. 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… hermitian-curves× 2 hashed-elgamal× 2 differential-privacy× 2 crl× 2 one of two common methods when using a public key infrastructure for maintaining access to servers in a network. niederreiter× 2 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 … pollard-rho× 2 prime-field× 2 present× 2 a lightweight block cipher with a 64-bit block size and an 80 or 128 bit key. kem× 2 For questions about Key Encapsulation Mechanisms (KEMs). KEMs are frequentely used in Cryptography to create public key encryption schemes and are a way to formalize a specific subset of hybrid encryp… isaac× 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. lucas× 2 traitor-tracing× 2 Traitor tracing describes an ability of specific cryptographic schemes that helps trace the source of leaks.
