Digital Signature Services (DSS) is an OASIS standard. As part of a Technical Committee (TC), specialising in “signature services”, a “Core” specification was created by the international standardization organization OASIS in 2007.
The Digital Signature Standard (DSS) is a Federal Information Processing Standard specifying a suite of algorithms that can be used to generate digital signatures established by the U.S. National Institute of Standards and Technology (NIST) in 1994.
In particular this also means that a message cannot contain hidden information that the signer is unaware of, and that can be revealed after the signature has been applied. WYSIWYS is a requirement for the validity of digital signatures, but this requirement is difficult to guarantee because of the increasing complexity of modern computer systems.
The Digital Signature Algorithm (DSA) is a public-key cryptosystem and Federal Information Processing Standard for digital signatures, based on the mathematical concept of modular exponentiation and the discrete logarithm problem.
The Payment Card Industry Data Security Standard (PCI DSS) consists of twelve significant requirements including multiple sub-requirements, which contain numerous directives against which businesses may measure their own payment card security policies, procedures and guidelines. [2] [3] [4] [5]
Each PCI DSS version has divided these six requirement groups differently, but the twelve requirements have not changed since the inception of the standard. Each requirement and sub-requirement is divided into three sections: PCI DSS requirements: Define the requirement. The PCI DSS endorsement is made when the requirement is implemented.
The Payment Application Data Security Standard (PA-DSS) is the global security standard created by the Payment Card Industry Security Standards Council (PCI SSC). [1] PA-DSS was implemented in an effort to provide the definitive data standard for software vendors that develop payment applications.
Tokenization, when applied to data security, is the process of substituting a sensitive data element with a non-sensitive equivalent, referred to as a token, that has no intrinsic or exploitable meaning or value. The token is a reference (i.e. identifier) that maps back to the sensitive data through a tokenization system.
