 ipsec× 9 key-rotation× 9 Key rotation refers to a schedule or process for changing the key material. memory-hard× 9 a property that, if proven to be possesed, makes an algorithm "immune" to time-memory tradeoffs, by "punishing" memory reductions. Usually algorithms possesing this property can't e… function-evaluation× 9 Calculating the value of a function for given inputs, especially, in the context of secure multi-party computation and/or homomorphic encryption, without disclosing the inputs to some or all parties c… decryption-oracle× 9 ripemd× 9 The RACE Integrity Primitives Evaluation Message Digest (RIPEMD) is a family of cryptographic hash functions. searchable-encryption× 8 a subfield of cryptography which constructs and analyzes cryptosystems that preserve the ability to 'search' over encrypted data, for some definition of 'search'. secure-channel× 8 smartcard× 8 simon× 8 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. siphash× 8 A fast 64-bit PRF that can be used as a MAC siv× 8 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… skein× 8 a cryptographic hash function. It was designed for the SHA-3 competition where it became a finalist, but wasn't chosen as SHA-3. distributed-decryption× 8 ecies× 8 Elliptic Curve Integrated Encryption Scheme (ECIES) is a public key encryption system proposed by Victor Shoup in 2001. file-format× 8 certificateless-crypto× 8 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 … key-wrap× 8 license-key× 8 a typically short alphanumeric code used as a software copy-protection mechanism, by requiring a user to enter a valid key before they can use the software. index-of-coincidence× 8 a measure of the relative frequency of letters in a cipher text sample, which facilitates cryptanalysis of poly-alphabetic ciphers by allowing determination of the per… literature× 7 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. mental-poker× 7 the common description for a set of cryptographic problems related to playing a fair game over a distance without the need for any trusted third party. probabilistic-encryption× 7 the use of randomness in an encryption algorithm, so that when encrypting the same message several times it will, in general, yield different ciphertexts. camellia× 7 a 128-bit, symmetrical block cipher jointly developed by Mitsubishi and NTT of Japan. congruence× 7 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 $m$.… blake2× 7 a cryptographic hash function. It was designed for the SHA-3 competition where it became a finalist, but wasn't chosen as SHA-3. access-control× 7 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. dual-ec-drbg× 7 short for Dual Elliptic Curve Deterministic Random Bit Generator; a pseudorandom number generator based on the elliptic curve discrete logarithm problem. timed-release× 7 Time-lock puzzles and other cryptographic schemes intended to ensure that a message cannot be read until a certain time has passed. resources× 7 material that can be referenced for further information on cryptography. ransomware× 7 universal-composability× 7 The framework of universal composability (UC) is a general-purpose model for the analysis of cryptographic protocols. truecrypt× 6 A famous program that was the de-facto standard for open-source disk encryption for many years. It was discontinued on 28 may 2014. TrueCrypt has undergone some security audits which haven't found sev… trusted-platform-module× 6 a secure coprocessor found in some x86-based computers that provides cryptographic operations and system integrity measurements. visual-cryptography× 6 Encrypting images so that they can be decrypted without using a computer, e.g. by superimposing two random-looking images. schnorr-identification× 6 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…
