Advanced Encryption Standard. Symmetric encryption algorithm specified by NIST in FIPS 197. As the result of a public evaluation, AES was declared the official encryption standard in the year 2001. It [..]

The term authentication is used to describe a procedure used by the participants of a communication in order to prove to each other that their participation is legitimate. An example for an authentica [..]

Certification Authority. Within a PKI, the CA is responsible for issuing digital certificates. See also: wikipedia: Certificate Authority

Digital proof that a certain public key (see asymmetric encryption) belongs to a specified entity, e.g. a person or organization. Certificates are usually issued by a trusted third party, a so-called [..]

Certificate Revocation List. Blacklist with the serial numbers of revoked certificates. A CRL is usually generated by a CA and then published. It refers to certificates issued by this CA.

Collective term for a combination of techniques for the prevention of unwanted data leakage. Among the techniques for Data Leakage Prevention are for example encryption, content filtering, mobile devi [..]

Federal Information Processing Standards. Series of publications edited by NIST which US industrial norms concerning information processing and information security are specified. Further information [..]

A hash algorithm resp. a hash function maps blocks of data of arbitrary length to blocks of a fixed length. The result of a hash algorithm using a cryptographic hash function is also called a digital [..]

In encryption technology, the bit length of a cryptographic key indicates the size of the so-called key space. The key space of an encryption algorithm with key length n consists of 2n cryptographic k [..]
