!!! Overview
[{$pagename}] ([COSE]) is defined in [RFC 8152] defines the CBOR Object Signing and Encryption (COSE) standard specified how to process [encryption], [signatures|Digital Signature], and [Message Authentication Code] ([MAC]) operations and how to encode keys using [CBOR]
[Concise Binary Object Representation] ([CBOR], [RFC 7049]) is a concise binary format for the serialization of data structured to an extended version of the [JSON] [data] model.
[{$pagename}] seeks to create [CBOR]-based [object signing|Digital Signature] and [encryption] formats. One motivation for [{$pagename}] was to reuse functionality from the [JOSE] working group using the [CBOR] data representation as it is more amenable to [Constrained Nodes] and [Constrained Networks] ([RFC 7228]).
The [JOSE] working group recently completed producing representations for [cryptographic] keys, [message authentication|Message Authentication Code] (MACs), [encryption], and [digital Signatures], using [JSON] representation.
The resulting formats will not be cryptographically convertible from or to [JOSE] formats. This lack of a need for bit-for-bit compatibility will enable some simplification in the adaptation process.
Criteria that should be considered in the decision making process, changing from [JSON] to [CBOR] encoding include:
* Maintain the current [JOSE] paradigms and formatting where feasible.
* Minimize message size, code size, and computational complexity to suit constrained environments, where this is expected to be used.
* Improve security
* Provide new functionality for additional use cases that were not required for [JOSE].
