A tag is a keyword or label that categorizes your question with other, similar questions. Using the right tags makes it easier for others to find and answer your question.

 Type to find tags:
 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 … 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 $A\in\mathcal{A}$ … libsodium× 2 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 diffusion× 2 Diffusion refers to the property of an encryption primitive that small changes in the plaintext result in big changes in the ciphertext and vice-versa. blake2× 2 a cryptographic hash function. It was designed for the SHA-3 competition where it became a finalist, but wasn't chosen as SHA-3. cpu× 2 the most important hardware component of a computer system, since it contains the circuitry necessary to interpret and execute instructions. cramer-shoup Cramer-Shoup asymmetric encryption (an extension of ElGamal) crl one of two common methods when using a public key infrastructure for maintaining access to servers in a network. blinding arx acoustic-cryptanalysis a type of side channel attack which exploits sounds emitted by computers or machines. differential-privacy dpa falsifiable-assumption lucas mulicast niederreiter 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 … oblivious-ram a useful primitive that allows a client to hide its data access patterns from an untrusted server in storage outsourcing applications. miracl md2 RFC 1319 — The MD2 Message-Digest Algorithm is a cryptographic hash function which is no longer considered secure. mars a 128-bit block cipher with variable key size of between 128 and 448 bits. It has a heterogeneous structure: several rounds of a cryptographic core are “jacketed” by un-keyed mixing rounds, to… rc2 a symmetric-key block cipher designed by Ron Rivest in 1987. rc6 a 128-bit block cipher, formerly an AES candidate, that makes heavy use of data-dependent rotations. rsap a variant of RSA, meant to increase the RSA public modulus size while keeping computation cost moderate. serialization shacal-2 shake sha-3-competition SHA-3 Competition (2007-2012) was a competition initiated by NIST as a call for a new cryptographic hash algorithm for standardization purposes. sstp a VPN tunneling protocol that allows the tunneling of PPP or L2TP traffic over an SSL connection. threefish A family of tweakable symmetric block-cipher algorithms with 256, 512 and 1024 bit block and key sizes. tokenization the process of breaking a stream of text up into words, phrases, symbols, or other meaningful elements called tokens. time-attack
