• Public key infrastructure — In cryptography, a public key infrastructure (PKI) is an arrangement that binds public keys with respective user identities by means of a certificate authority (CA). The user identity must be unique for each CA. The binding is established through …   Wikipedia

• Public-key cryptography — In an asymmetric key encryption scheme, anyone can encrypt messages using the public key, but only the holder of the paired private key can decrypt. Security depends on the secrecy of that private key …   Wikipedia

• Public key certificate — Diagram of an example usage of digital certificate In cryptography, a public key certificate (also known as a digital certificate or identity certificate) is an electronic document which uses a digital signature to bind a public key with an… …   Wikipedia

• Cryptographic Message Syntax — (CMS) ist ein Standard vom IETF für gesicherte kryptographische Mitteilungen. CMS ist die Obermenge des PKCS #7 (Public Key Cryptography Standards #7) welche auf S/MIME aufsetzt. Der Version 2 lag der gleiche Standard zugrunde. Ab Version 3… …   Deutsch Wikipedia

• Key Wrap — constructions are a class of symmetric encryption algorithms designed to encapsulate (encrypt) cryptographic key material. The Key Wrap algorithms are intended for applications such as (a) protecting keys while in untrusted storage, or (b)… …   Wikipedia

• Cryptographic engineering — is the discipline of using cryptography to solve human problems. Cryptography is typically applied when trying to ensure data confidentiality, to authenticate people or devices, or to verify data integrity in risky environments. Cryptographic… …   Wikipedia

• Key management — is a term used to describe two different fields; (1) cryptography, and (2) physical key management (or electronic key management) within building or campus access control.In cryptography, key management includes all of the provisions made in a… …   Wikipedia

• Key size — In cryptography, key size or key length is the size measured in bits[1] of the key used in a cryptographic algorithm (such as a cipher). An algorithm s key length is distinct from its cryptographic security, which is a logarithmic measure of the… …   Wikipedia

• Cryptographic Service Provider — In Microsoft Windows, a Cryptographic Service Provider (CSP) is a software library that implements the Microsoft CryptoAPI (CAPI). CSPs implement encoding and decoding functions, which computer application programs may use, for example, to… …   Wikipedia

• Cryptographic Message Syntax — The Cryptographic Message Syntax (CMS) is the IETF s standard for cryptographically protected messages. It can be used to digitally sign, digest, authenticate or encrypt any form of digital data. CMS is based on the syntax of PKCS#7, which in… …   Wikipedia
