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:
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 128-bit block cipher, formerly an AES candidate, that makes heavy use of data-dependent rotations.
a symmetric-key block cipher designed by Ron Rivest in 1987.
a variant of RSA, meant to increase the RSA public modulus size while keeping computation cost moderate.
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.
The Cryptographic Application Programming Interface is an application programming interface included with Microsoft Windows operating systems that provides services to enable developers to secure Wind…
a type of side channel attack which exploits sounds emitted by computers or machines.
a cryptographic hash function. It was designed for the SHA-3 competition where it became a finalist, but wasn't chosen as SHA-3.
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.
