Internet Engineering Task Force (IETF) Phillip Hallam-Baker INTERNET-DRAFT Comodo Group Inc. Intended Status: Standards Track March 25, 2015 Expires: September 26, 2015 JOSE Direct Compact Serialization draft-hallambaker-joseunencoded-01 Abstract An alternative serialization for JOSE signatures is presented in which the headers, signature and payload are encoded directly, without Base64 encoding. Use of this format requires the use of a binary transport that does not Status of This Memo This Internet-Draft is submitted in full conformance with the provisions of BCP 78 and BCP 79.

Definitions 1.1. Requirements Language The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in RFC 2119 [RFC2119]. 2. Serialization In the JWS Direct Serialization, no JWS Unprotected Header is used. In this case, the JOSE Header and the JWS Protected Header are the same. In the JWS Direct Serialization, a JWS is represented as the concatenation: UTF8(JWS Protected Header)) || '.' || (JWS Payload) || '.' || (JWS Signature) The calculation of the signature is performed over the octet sequence that corresponds to the concatenation: UTF8(JWS Protected Header)) || '.' || (JWS Payload) || '.' 3. Acknowledgements Mike Jones provided advice on an early version of this proposal. 4. Security Considerations The security considerations presented in [I-D.ietf-jose-json-web- signature] apply. 5. IANA Considerations Type name: application Subtype name: jose+direct Required parameters: n/a Optional parameters: n/a Encoding considerations: 8bit; application/jose+direct values are represented as a JSON Object; UTF-8 encoding SHOULD be employed for the JSON object.
