Page : 6/160 A. FOREWORD

Page : 7/160 1. Introduction 1.1 Purpose of the document This document is intended for the end user who wants to access RTE s Information System by using software certificates under Microsoft Windows Seven. This document allows the holder to: Understand the context and principles of a secure environment (authentication, confidentiality, integrity and non-repudiation) and the general operation of a Public Key management Infrastructure (PKI). Learn to install and use his software certificates in the following environments: o o o Microsoft Windows Seven. Browsers: Internet Explorer and Mozilla Firefox for secure accesses via the HTTPS protocol. Email Clients: Microsoft Outlook, IBM Lotus Notes, and Mozilla Thunderbird for secure exchanges in S/MIME format (a standard for cryptography and digital signatures concerning emails encapsulated in MIME format). NOTE Throughout this document, the word "you" is the user of the certificate. 1.2 Context Under the law of February 10, 2000 (2000-108) and the implementing decree 2001-630 of 16 July 2001, the operator of the public transport network has an obligation to preserve the confidentiality of economic, commercial, industrial, financial or technical information of which the disclosure would be likely to undermine the rules of free and fair competition and nondiscrimination required by law. 1.3 Warning regarding security practices Each software certificate holder has its own private key, all (certificate and associated private key) is generated by RTE and made available for download by the wearer as a passwordprotected file (PKCS # 12 file, extension "p12"). Then, each software certificate holder shall take all necessary precautions to prevent: the violation of his private key, the loss of his private key, the divulgation of his private key, the alteration of his certificate, the misuse of his certificate. Each software private key and its associated certificate have to be stored on hard disk and protected by a password known only by the certificate holder.

Page : 8/160 The Certification Authority (CA) "RTE Certification Authority" takes no responsibility for disputes related to misuse of private keys. 1.4 The actors The life cycle management of a certificate is based on three entities: the client (i.e. your company), the Registration Authority (RA), the Certification Authority (CA). NOTE To understand, one can draw a parallel with the allocation of official credentials: the applicant citizen of a credential is the Client; the town is the Registration Authority and the prefecture is the Certification Authority. The client The client issues certificates requests for holders. It may also issue requests for revocation of the certificates (see Section B: certificate management procedures). Registration Authority (RA) The Registration Authority (RTE s manager of customer relations and the Operator) collects the certificates requests, affixes a date of validity for certificates and verifies the identity of their holders. Certification Authority (CA) The Certification Authority (RTE) is responsible and liable for certificates signed in its name and of the PKI s operation. It sets policy for the management and use of certificates. RTE certification authority is called: CN = RTE Certification Authority, O = RESEAU DE TRANSPORT D'ELECTRICITE

B. CERTIFICATES MANAGEMENT PROCEDURES Programmes & SI (PSI) TOUR MARCHAND 41 RUE BERTHELOT - 92411 COURBEVOIE CEDEX TEL : 01.78.66.50.00 - FAX : 01.78.66.50.64 www.rte-france.com/en/ 05-09-00-LONG

Page : 10/160 2. Certificates management process 2.1 Foreword The main processes used to manage all the digital certificates issued to holders are: obtaining a certificate (obtaining one or more certificates), renewal of a certificate (replacement by a new certificate for a new validity period and a new key pair) revocation of a certificate (end of certificate validity). 2.2 Software certificate request Preliminary steps Beforehand, the following steps must be performed, The company representative issues an access request : The company representative must have completed and signed the request forms access to RTE IS services and applications" sent by his Customer Relations Manager, and then sent it back to him. In these forms, the company representative specifies in particular: o a Contact email who will receive all information necessary to retrieve the certificate (see Erreur! Source du renvoi introuvable.), o a Certificate email, o a Chosen password, necessary to the retrieval of the certificate by the holder We have registered your request : Following receipt of the forms we have created your account(s) to access the applications.

Page : 11/160 General diagram After the certificate request has been saved and validated by us (within 5 working days), a notification email is sent to the address "Contact Email" entered in the access request form (see 2.2.1). This mall is entitled "Access to RTE s IS services" and contains: a summary of the certificate of removal procedure, the "Certificate email" and "Retrieval Code" requested by the website to retrieve your certificate, the Password" protecting the PKCS # 12 file (a ".p12" extension) that you downloaded when you retrieved your certificate. Please remember that this password is different from the password to retrieve the certificate. In case of loss or non-receipt of this message, contact the RTE Hotline. Exchange scenarios The holder has to connect from his workstation on the certificate retrieval website and download his private key and the associated certificate to his workstation in the form of the PKCS#12 file (extension "p12"). 2.3 Certificates renewal The lifespan of the certificates is limited to 3 years, to ensure a high level of security. Forty days before the expiration date of a certificate, an electronic message is sent to the contact email to inform the holder of the forthcoming expiry of his software certificate. In case, changes must be made concerning the holder s information, then the company representative contacts RTE s responsible for customer relations to inform him of the changes. Otherwise, an email is sent to the contact email with the information necessary for the retrieval of his new certificate.

Page : 12/160 2.4 Revocation of certificates Case of revocation The company representative must issue a revocation request when any of the following occurs: Change of the holder, Loss, theft, compromise or suspected compromise (possible, probable or certain) of his private key or associated certificate, Death or cessation of business of the certificate holder, Loss of the activation data, defective or lost support. Revocation request To revoke a certificate, the company representative should call the RTE Hotline. When the certificate is revoked, an email is sent to the contact email to notify the holder of the revocation of his certificate.

Page : 14/160 3. Installation and configuration of the workstation All operations of this chapter are to be performed only once by a computer specialist with Administrator privileges on your workstation, upon receipt of your "PKI Access Kit". Also note that only a few chapters of this manual concern you: the chapters corresponding to the software you use. All operations are done under the Windows Session of the certificate holder. 3.1 Network configuration General configuration The web browser access uses - in a way that is transparent to the user - a software certificate authentication system for access to the RTE portal and encryption of data exchanged via the Internet (HTTPS protocol). Mail exchanges between RTE and the user are routed over the Internet (SMTP protocol, S/MIME format). Specificity of the VPN access IMPORTANT NOTE Messaging and antivirus gateways, firewalls and content analyzers should be configured not to alter or reject messages that are encrypted and signed S/MIME (application / x-pkcs7-mime,.p7s,.p7m) and not to prohibit the flow of HTTPS data (port 443). The network administrator may be requested to perform these operations. The VPN allows from your workstation to establish a secure connection (based on the authentication to a dedicated site) to RTE s IS via the Internet. Access to the SSL VPN requires that your workstation can resolve the address secure.iservices.rte-france.com. To see if this is the case, open your Start menu, type run in the search bar and click the icon "Run."

This channel is established after authenticating with your certificate from a dedicated website (see section 5.4). Once the channel is established all communications with the requested RTE service will be encrypted. The use of SSL VPN requires the installation of a dedicated tool, installed during the first login to the site. The application is called Windows Secure Application Manager (WSAM). SSL VPN enables secure access to your mailboxes hosted on RTE s FrontOffice.

Page : 88/160 Prerequisite In order to connect to the SSL VPN with Firefox, Java SE Runtime Environment (JRE) 1.5.07 or higher needs to be installed on your workstation. If this is not the case, you can download the latest version on Oracle s website: http://java.com/fr/download/index.jsp IMPORTANT NOTE Before your first connection, you must verify that your workstation can resolve the address secure.iservices.rte-france.com (see section 3.1).

The Email account configuration in your mail client is then to be made with the following parameters: Mail server type : POP Server POP server address : pop.services.rte-france.com SMTP server address : smtp.services.rte-france.com When your access to RTE s FrontOffice is provided, you will receive your login name, your password and your email address. NOTE Because the messages are transferred through a secure channel, sending and receiving messages do not require the use of a certificate to encrypt messages.

Page : 98/160 E. EMAIL EXCHANGES WITH RTE S INFORMATION SYSTEM This section only applies if you need to exchange signed-encrypted email with RTE applications. After reading the chapter 6 (overview), directly refer to the chapter associated with the email client that you use for your mail exchanges with RTE: Chapter 7 if you use Microsoft Outlook 201 as email client. Chapter 8 if you use Mozilla Thunderbird as email client. Chapter 9 if you use Lotus Notes 8.5 as email client. Chapter 10 if you use Lotus Notes 9 as email client.

Page : 99/160 6. Using your certificate to exchange emails 6.1 Certificate usage principle Using your personal certificate, its associated private key, RTE s CA certificate and RTE s application certificate, you can: decrypt and verify the signature of emails you receive from RTE applications, encrypt and sign emails you send to RTE applications. 6.2 Decryption and signature verification of a received message Decryption and verification of the signature of a message are disjoint processes. When you receive an encrypted-signed message: you decrypt the message with the private key associated to your personal certificate, you verify the message signature with the certificate of the sender (that of the RTE application) contained in the message, and with the certificate you own of the issuing CA that you trust. These two processes are done automatically when you open a signed-encrypted email with a properly configured email client that supports the secure email format S/MIME. IMPORTANT NOTE To verify the signature of a message you need to own the right certificate and trust the CA that issued the certificate of the sender. 6.3 Encryption and signing of a sent message Encrypting and signing message are two disjoint processes. When you send an encryptedsigned message: you sign the message with the private key associated to your personal certificate, you encrypt the message with the recipient s certificate (RTE s application certificate). The certificate of the recipient can be obtained in several ways. RTE applications transmit to you their certificate by sending a signed message: that is the way you will get their certificate. In doing so, when you receive a signed message, use "Add sender to contacts" to save at the same time its certificate, which you can use to send encrypted messages to him. IMPORTANT NOTE Encrypting a message requires to possess a valid certificate corresponding to the recipient's email address.

Page : 100/160 6.4 Steps to configure your email client In order to be able to exchange signed-encrypted emails with RTE, the steps are as follows: Install RTE s CA certificate, so that your mail client trusts RTE s applications certificates and is able to verify the signature of signed-encrypted emails you receive from them. Install your personal certificate, so your mail client can decrypt the messages from RTE and sign messages to RTE. Configure the email account you will use to exchange with RTE so that your email client always encrypts and signs messages to the RTE applications using the standard S/MIME. Install RTE s application certificate, so that your email client can encrypt emails you send to RTE applications. To perform these steps, please refer directly to one of the following chapters: the one concerning the email client that you use for your mail exchanges with RTE.
