CMS is a general framework for electronic signatures for various kinds of transactions like purchase requisition, contracts or invoices. [2] CAdES specifies precise profiles of CMS signed data making it compliant with the European eIDAS regulation (Regulation on electronic identification and trust services for electronic transactions in the internal market).
The Cryptographic Message Syntax (CMS) is the IETF's standard for cryptographically protected messages. It can be used by cryptographic schemes and protocols to digitally sign , digest , authenticate or encrypt any form of digital data.
CAdES, CMS Advanced Electronic Signatures is a set of extensions to Cryptographic Message Syntax (CMS) signed data, making it suitable for Advanced Electronic Signatures. JAdES, JSON Advanced Electronic Signatures is a set of extensions to JSON Web Signature (RFC 7515) making it suitable for Advanced Electronic Signatures. ASiC Baseline Profile.
An electronic signature, or e-signature, is data that is logically associated with other data and which is used by the signatory to sign the associated data. [1] [2] [3] This type of signature has the same legal standing as a handwritten signature as long as it adheres to the requirements of the specific regulation under which it was created (e.g., eIDAS in the European Union, NIST-DSS in the ...
One of the purposes of an electronic signature is to secure the data that it is attached to it from being modified. This can be done by creating a dataset that combines the signature with its signed data or to store the detached signature to a separate resource and then utilize an external process to re-associate the signature with its data.
Availability of electronic signature techniques has already been a major stimulus to eBusiness and eGovernment. Digital signatures are a secure and legally binding means to implement electronic signatures through three cryptographic algorithms: [5] the key generating algorithm that randomly selects a private key and its corresponding public key

Due to the wide range of requirements from the various application areas of signatures and time-stamps, the core specification has been extended by a series of so-called “profiles”, e.g. for use with code signing, entity seals or processing XAdES- and CAdES-compliant artifacts. In the following years further profiles were developed, e.g ...
