 decryption-oracle× 6 congruence× 6 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 $m$.… secure-storage× 6 Secure storage describes storing resources in a secure way, so that they are only available to authorized users and trusted networks. universal-hash× 6 wpa2-psk× 6 Wi-Fi Protected Access 2 - Pre-Shared Key (also called WPA or WPA2 Personal) is a method of securing your network using WPA2 with the use of the optional Pre-Shared Key (PSK) authentication, which was… searchable-encryption× 5 a subfield of cryptography which constructs and analyzes cryptosystems that preserve the ability to 'search' over encrypted data, for some definition of 'search'. siv× 5 a two-pass AEAD block cipher mode of operation described in RFC 5297. It can be used either for key-wrap (nonce-less deterministic authenticated encryption) or… s-mime× 5 Secure/Multipurpose Internet Mail Extensions, or short S-MIME, is a standard for public key encryption and signing of MIME data. constants× 5 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. certificateless-crypto× 5 a variant of ID-based cryptography intended to prevent the key escrow problem. Only a partial private key is generated by the key generation center (KGC) and the other … dual-ec-drgb× 5 short for Dual Elliptic Curve Deterministic Random Bit Generator; a pseudorandom number generator based on the elliptic curve discrete logarithm problem. hardness-assumptions× 5 needham-schroeder× 5 Needham–Schroeder refers to both, a symmetric key or a public key authentication protocol. information-theory× 5 concerned with sending messages via electronic signals in the most efficient and error-free way. literature× 5 Literature describes everything that has been written and/or visualized (here: in relation cryptography), which ranges from papers to books, and from publications to presentations. key-wrap× 5 knapsack× 5 the problem of determining which numbers from a given collection of numbers have been added together to yield a specific sum: used in cryptography to encipher (and sometimes decipher) mess… schnorr-identification× 5 The Schnorr Identification Protocol relies upon the security of the Discrete Logarithm Problem. Schnorr's protocol was introduced after, and is comparable to, the identification protocol of Fiat and S… resources× 5 material that can be referenced for further information on cryptography. proxy-re-encryption× 5 predicate-encryption× 4 an encryption paradigm which gives a master secret key owner fine-grained control over access to encrypted data. luby-rackoff× 4 a Feistel cipher where in each round the nonlinear function used is assumed to be chosen uniformly at random from the set of all such functions. These ciphers are mainly of th… key-recovery× 4 A means of recovering cryptographic keys when the usual means for obtaining them is unavailable.; the ability to uncover the secret key to a cryptographic message. key-escrow× 4 key-check-value× 4 ocb× 4 The Offset CodeBook Mode, an authenticated encryption mode of operation for a block cipher. ecies× 4 Elliptic Curve Integrated Encryption Scheme (ECIES) is a public key encryption system proposed by Victor Shoup in 2001. education× 4 Questions related to the teaching and learning of cryptography. embedded× 4 a computer system with a dedicated function within a larger mechanical or electrical system, often with real-time computing constraints. avalanche× 4 evident if, when an input is changed slightly (for example, flipping a single bit) the output changes significantly (e.g., half the output bits flip). camellia× 4 a 128-bit, symmetrical block cipher jointly developed by Mitsubishi and NTT of Japan. simon× 4 A family of lightweight symmetric block-ciphers designed for good performance in hardware with block sizes ranging from 32 to 128 bits and key sizes ranging from 64 to 256 bits. speck× 4 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. tea× 4 a block cipher by David Wheeler and Roger Needham of the Cambridge Computer Laboratory; notable for its simplicity of description and implementation. 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
