ANNEX

Technical specifications, measures and other requirements of the decentralised IT system referred to in Article 1

1.   Introduction

The Taking of Evidence (ToE) exchange system is an e-CODEX based decentralised IT system that can carry out exchanges of documents and messages related to the taking of evidence between the different Member States in accordance with Regulation (EU) 2020/1783. The decentralised nature of the IT system would enable data exchanges exclusively between one Member State and another, without any of the Union institutions being involved in those exchanges.

2.   Definitions

| 2.1. | ‘HyperText Transport Protocol Secure’ or ‘HTTPS’ means encrypted communication and secure connection channels; |
| --- | --- |

2.1.

| 2.2. | ‘Portal’ means the Reference Implementation solution or the National Back-end solution connected to the decentralised IT system; |
| --- | --- |

2.2.

| 2.3. | ‘Non-repudiation of origin’ means the measures providing the proof of the integrity and proof of origin of the data through methods such as digital certification, public key infrastructure and digital signatures; |
| --- | --- |

2.3.

| 2.4. | ‘Non-repudiation of receipt’ means the measures providing the proof of the receipt of the data to the originator by the intended recipient of the data through methods such as digital certification, public key infrastructure and digital signatures; |
| --- | --- |

2.4.

| 2.5. | ‘SOAP’ means, as per the standards of World Wide Web Consortium, a messaging protocol specification for exchanging structured information in the implementation of web services in computer networks; |
| --- | --- |

2.5.

| 2.6. | ‘Web service’ means a software system designed to support interoperable machine-to-machine interaction over a network; it has an interface described in a machine-processable format; |
| --- | --- |

2.6.

| 2.7. | ‘data exchange’ means the exchange of messages and documents through the decentralised IT system. |
| --- | --- |

2.7.

3.   Methods of communication by electronic means

The ToE exchange system shall use service-based methods of communication, such as Web-services or other reusable Digital Service Infrastructures for the purpose of exchanging messages and documents.

Specifically, it will use the e-CODEX infrastructure, which is comprised of two major components, the Connector and the Gateway.

The Connector is responsible for handling communication with the Reference Implementation solution or national implementations. It can process message exchange with the Gateway in both directions, trace messages and acknowledge them using standards such as ETSI-REM evidences, validate signatures of business documents, create a token that holds the outcome of the validation in PDF and XML format and create a container using standards such as ASIC-S where the business content of a message is packed and signed.

The Gateway is responsible for the exchange of messages and it is agnostic of the message content. It can send and receive messages to and from the Connector, validate header information, identify correct processing mode, sign and encrypt messages and transfer messages to other Gateways.

4.   Communication protocols

The ToE exchange system shall use secure internet protocols, such as HTTPS for portal and decentralised IT system components communication and the standard communication protocols, such as SOAP, for the transmission of structured data and metadata.

Specifically, e-CODEX provides a strong information security by taking advantage of state of the art authentication and multilayer cryptographic protocol.

5.   Security standards

For the communication and distribution of information via the ToE exchange system, the technical measures for ensuring minimum information technology security standards shall include:

| (a) | measures to ensure confidentiality of information, including by using secure channels (HTTPS); |
