4.1 Signature creation process steps and data elements
Figure 1 (derived from ETSI EN 319 102-1 [i.12], clause 4.2.1) shows the various steps and the related data elements for a signature creation process. For remote signature creation, different steps of this process are carried out according to a decomposition into several components, which will have access to or make av...

4.2 Service main components and interfaces
The above process points out scenarios where the AdES and/or Digital Signature Value (DSV) are created using a signing key held within a cryptographic security module named Signature Creation Device (SCDev) operated by a Signature Creation Service Provider (SCSP). Based on the different types of data managed in request...

119 432
4.3.1 Signer's document and hashing
The signature creation process starts with the signer's document (SD), which is to be signed. The SD is represented (SDR) by a hash value in the Data To Be Signed (DTBS). The following observations are made: • The creation of the SDR (the hashing) can be done where the SD is stored or by the SCASC. In the former case, ...

4.3.2 DTBS composition and formatting
In the two processes of DTBS composition and formatting, which in the context of the present document are considered together, the SDR (hash of the document to be signed or hash of a formatted version of the document to be signed) and hashes of signed attributes/properties are assembled into the Data To Be Signed Forma...

4.3.3 DTBS preparation
This step consists of creating the DTBSR from the DTBSF. The SCASC prepares the entire DTBSF, calculates the hash, and sends the hash value (DTBSR) as input to an SSASC.

4.3.4 SDO composer
As the final step, the SDO (the AdES format) is constructed. This consists of combining the digital signature value with other parameters into the requested format. Depending on the format, the digital signature made available for the SD is named: • Enveloped: The signature is added to the SD (e.g. PAdES signature). • ...

4.4.1.1 Introduction
The purpose of the signature creation process is to take the DTBSR and create a digital signature value under the control of the signer. In the context of the present document, the creation of the digital signature value is managed by an SSASC that uses a signing key, held within a cryptographic security module (SCDev)...

4.4.1.2 Signature activation
The SSASC uses a remote SCDev to generate, maintain and use the signing keys under the control of their authorized signers. The authorized signer remotely controls the signing key with a certain level of confidence possibly by means of the Signature Activation Module (SAM). The SAM is a software component using the Sig...

4.4.1.3 Signature creation by SCDev
The signature creation process is performed by the SCDev. In the context of the present document, only architectures where the signature creation process is carried out by a remote SCDev are considered. According to the above sole control assurance levels the signing key can be used to generate the digital signature va...

5.1 Introduction
The present document recommends protecting remote signature creation services from unauthorized access. Any driving application shall be authenticated when invoking a signature creation service. In order to create signatures an authorization from the user who owns and controls the signing key is required. The user may ...

5.2.1 Overview
Various types of authorization mechanisms may be supported, and the driving application shall adopt any of those available from the signature creation service.

5.2.2 HTTP Basic Authentication and HTTP Digest Authentication
NOTE: HTTP Basic Authentication [i.10] is an unsafe mechanism, and therefore it should not be used, especially by driving application running as a service. It should only be used when there is a high degree of trust between the user and driving application and when other authorization types are not available. This mech...

5.2.3 OAuth 2.0
When the authentication is under the control of the signature creation service the signature creation service may adopt an indirect way of authorizing access to the API by using OAuth 2.0 [17] that is primarily an authorization framework, but that can also be leveraged for authentication when interacting with a signatu...

5.2.4 Other authentication mechanisms
The underlying communication between the driving application and the signature creation service may ensure access control in some other different ways than OAuth 2.0 or HTTP Basic or Digest Authentication. The following alternatives can be considered for authenticating clients to a signature creation service: • Mutual ...

5.3.1 Overview
Requesting signatures creation to a signature creation service requires an authorization from the user who owns and controls the signing key to be used for signatures creation. The user might authorize signatures creation with an already existing signing key or with a signing key to be created on-the-fly. Two different...

5.3.3 Create a remote signature with a credential protected by OAuth2
OAuth 2.0 authorization is a widely used framework that allows applications to obtain limited access to a user's resources on a service, without needing the user's authentication data (i.e. the user's password). OAuth 2.0 can provide client applications a secure delegated access to server resources on behalf of a resou...

5.4 Credential creation authorization
Requesting credential creation to the signature creation service requires an authorization from the user to whom the credential to be created will be bound. CSC API [1] only supports OAuth 2.0 authorization to grant credential creation authorization. Figure 6: A general flow involving a driving application requesting s...

5.5 Credential deletion authorization
A credential may be deleted for various reasons: • End of lifecycle: the credential is no longer needed or has expired. • Security reasons: the credential may be compromised or the user requests revocation. • Regulatory compliance: certain frameworks require deletion because of cryptographic algorithms obsolescence Req...
