 key-rotation× 3 Key rotation refers to a schedule or process for changing the key material. kbkdf× 3 a key derivation function ([tag:kdf]) that uses a key in the computation. ecies× 3 Elliptic Curve Integrated Encryption Scheme (ECIES) is a public key encryption system proposed by Victor Shoup in 2001. file-format× 3 feal× 3 a block cipher designed by NTT. It is known to be insecure. 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… 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 … alternating-step× 3 a cryptographic pseudorandom number generator intended to be used in a stream cipher. 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… verifiability× 3 universal-composability× 3 The framework of universal composability (UC) is a general-purpose model for the analysis of cryptographic protocols. three-pass-protocol× 3 The three-pass protocol uses commutative encryption to let two people communicate privately without having to exchange keys in advance. truecrypt× 2 xml-encryption× 2 Encryption of data represented in XML according to the W3C Specification. voip× 2 a technology that allows telephone calls to be made over computer networks like the Internet. untagged× 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. sponge-function× 2 skipjack× 2 a 64-bit block cipher developed by the U.S. National Security Agency (NSA). smartcard× 2 access-control× 2 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. cpu× 2 the most important hardware component of a computer system, since it contains the circuitry necessary to interpret and execute instructions. 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… homomorphic-signatures× 2 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… hermitian-curves× 2 hashed-elgamal× 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. desx× 2 an extension of DES that attempts to foil brute force attacks 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 … 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://… secure-index× 2 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. rc6 a 128-bit block cipher, formerly an AES candidate, that makes heavy use of data-dependent rotations.
