 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… key-schedule× 3 an algorithm that expands a relatively short master key to a relatively large expanded key for later use in an encryption and decryption algorithm. needham-schroeder× 3 Needham–Schroeder refers to both, a symmetric key or a public key authentication protocol. ocb× 3 The Offset CodeBook Mode, an authenticated encryption mode of operation for a block cipher. montgomery× 3 onion-routing× 3 A method for anonymous communications over a wide area network such as the Internet. decryption-oracle× 3 cfb× 3 an encryption mode, that builds a self-synchronizing stream-cipher from a block-cipher. biclique-attack× 3 bijection× 3 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 … fiat-shamir× 3 distributed-decryption× 3 information-theory× 3 concerned with sending messages via electronic signals in the most efficient and error-free way. transposition-cipher× 3 A classical cipher in which the ciphertext is obtained by scrambling the letters of the plaintext. 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… voip× 2 a technology that allows telephone calls to be made over computer networks like the Internet. xml-encryption× 2 Encryption of data represented in XML according to the W3C Specification. universal-composability× 2 universal-hash× 2 speck× 2 A family of lightweight symmetric block-ciphers designed for good performance in constrained software devices with block sizes ranging from 32 to 128 bits and key sizes ranging from 64 to 256 bits. three-pass-protocol× 2 The three-pass protocol uses commutative encryption to let two people communicate privately without having to exchange keys in advance. 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… ipsec× 2 hermitian-curves× 2 hashed-elgamal× 2 double-encryption× 2 alternating-step× 2 a cryptographic pseudorandom number generator intended to be used in a stream cipher. cmac× 2 a block cipher-based message authentication code algorithm. 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 $m$.… constants× 2 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. cpu× 2 the most important hardware component of a computer system, since it contains the circuitry necessary to interpret and execute instructions. 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 … 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 … 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 $A\in\mathcal{A}$ … key-rotation× 2 Key rotation refers to a schedule or process for changing the key material. key-escrow× 2
