 mixing-function× 3 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… 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… kbkdf× 3 a key derivation function ([tag:kdf]) that uses a key in the computation. key-rotation× 3 Key rotation refers to a schedule or process for changing the key material. plausible-deniability× 3 Plausible deniability may refer $1)$ to deniable encryption schemes allowing to decrypt a ciphertext for a message $m$ to some distinct message $m'$ or $2)$ to a feature provided by deniable file syst… pir× 3 A PIR (Private Information Retrieval) protocol allows a user to retrieve an item from a server in possession of a database without revealing which item is retrieved. onion-routing× 3 A method for anonymous communications over a wide area network such as the Internet. 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 … access-control× 3 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. alternating-step× 3 a cryptographic pseudorandom number generator intended to be used in a stream cipher. hamming× 3 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… hashed-elgamal× 3 hybrid× 3 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… homomorphic-signatures× 3 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… feal× 3 a block cipher designed by NTT. It is known to be insecure. file-format× 3 three-pass-protocol× 3 The three-pass protocol uses commutative encryption to let two people communicate privately without having to exchange keys in advance. untagged× 3 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… universal-composability× 3 The framework of universal composability (UC) is a general-purpose model for the analysis of cryptographic protocols. speck× 3 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. skipjack× 2 a 64-bit block cipher developed by the U.S. National Security Agency (NSA). smartcard× 2 sponge-function× 2 secure-index× 2 xml-encryption× 2 Encryption of data represented in XML according to the W3C Specification. traffic-analysis× 2 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… truecrypt× 2 unicity-distance× 2 the average amount of ciphertext a computationally unlimited attacker needs to obtain in order to uniquely determine the correct decryption. theory× 2 voip× 2 a technology that allows telephone calls to be made over computer networks like the Internet. hermitian-curves× 2 ephemeral× 2 short-lived, like (for example) an ephemeral key, which is a key that only exists within the lifetime of a communication session. error-propagation× 2 desx× 2 an extension of DES that attempts to foil brute force attacks
