The Miyaguchi-Preneel scheme, based on a one-way compression function, was proposed around 1989 by Preneel, and independently by Miyaguchi.Ohta, and Iwata.

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 $A\in\mathcal{A}$ …

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 …
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 …
a useful primitive that allows a client to hide its data access patterns from an untrusted server in storage outsourcing applications.
RFC 1319 — The MD2 Message-Digest Algorithm is a cryptographic hash function which is no longer considered secure.
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…
a variant of RSA, meant to increase the RSA public modulus size while keeping computation cost moderate.
a symmetric-key block cipher designed by Ron Rivest in 1987.
a 128-bit block cipher, formerly an AES candidate, that makes heavy use of data-dependent rotations.
Cramer-Shoup asymmetric encryption (an extension of ElGamal)
one of two common methods when using a public key infrastructure for maintaining access to servers in a network.
a type of side channel attack which exploits sounds emitted by computers or machines.
SHA-3 Competition (2007-2012) was a competition initiated by NIST as a call for a new cryptographic hash algorithm for standardization purposes.
a VPN tunneling protocol that allows the tunneling of PPP or L2TP traffic over an SSL connection.
the process of breaking a stream of text up into words, phrases, symbols, or other meaningful elements called tokens.
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…
Traitor tracing describes an ability of specific cryptographic schemes that helps trace the source of leaks.
A family of tweakable symmetric block-cipher algorithms with 256, 512 and 1024 bit block and key sizes.
