Batch cryptography is a field of cryptology focused on the design of cryptographic protocols that perform operations—such as encryption, decryption, key exchange, and authentication—on multiple inputs simultaneously, rather than processing each...
The following outline is provided as an overview of and topical guide to cryptography: Cryptography (or cryptology) – practice and study of hiding information. Modern cryptography intersects the disciplines of mathematics, computer science, and...
Homomorphic encryption is a form of encryption that allows computations to be performed on encrypted data without first having to decrypt it. The result of the computations are left in an encrypted form which, when decrypted, result in an output...
In cryptography, ciphertext or cyphertext is the result of encryption performed on plaintext using an algorithm, called a cipher. Ciphertext is also known as encrypted or encoded information because it contains a form of the original plaintext that...
The OpenBSD Cryptographic Framework (OCF) is a service virtualization layer for the uniform management of cryptographic hardware by an operating system. It is part of the OpenBSD Project, having been included in the operating system since OpenBSD...
Provable security refers to any type or level of computer security that can be proved. It is used in different ways by different fields. Usually, this refers to mathematical proofs, which are common in cryptography.
David Lee Chaum (born 1955) is an American computer scientist, cryptographer, and inventor. He is known as a pioneer in cryptography and privacy-preserving technologies and widely recognized as the inventor of digital cash. His 1982 dissertation,...
Pretty Good Privacy (PGP) is an encryption program that provides cryptographic privacy and authentication for data communication. PGP is used for signing, encrypting, and decrypting texts, e-mails, files, directories, and whole disk partitions and...
In public-key cryptography, Edwards-curve Digital Signature Algorithm (EdDSA) is a digital signature scheme using a variant of Schnorr signature based on twisted Edwards curves. It is designed to be faster than existing digital signature schemes...
Nym is an evolving mix network (mixnet), a type of computer network infrastructure for privacy that masks user metadata, separating source and destination IP addresses. It anonymizes various types of communication, including messaging, files...
