Summary

DescriptionPublic-Key-Infrastructure.svg	English: Principle of a public key infrastructure. CA: certification authority, RA: registration authority, VA: validation authority Rough outline: A user applies for a certificate with his public key at a registration authority (RA). The latter confirms the user's identity to the certification authority (CA) which in turn issues the certificate. The user can then digitally sign a contract using his new certificate. His identity is then checked by the contracting party with a validation authority (VA) which again receives information about issued certificates by the certification authority. Français : Infrastructure à clés publiques CA : Autorité de certification, RA : Autorité d'enregistrement, VA : Autorité de Validation. Grossièrement : Un utilisateur demande un certificat avec sa clé publique à une autorité d'enregistrement (RA). Cette dernière confirme l'identité de l'utilisateur à l'autorité de certification (CA) qui, à son tour, émet le certificat. L'utilisateur peut alors signer numériquement un contrat en utilisant son nouveau certificat. Son identité est ensuite vérifiée par la partie contractante auprès d'une autorité de validation (VA) qui reçoit à nouveau des informations sur les certificats émis par l'autorité de certification. Español: Infraestructura de clave pública CA: Autoridad de Certificación, RA: Autoridad de Registro, VA: Autoridad de Validación. A grandes rasgos: Un usuario solicita un certificado con su clave pública a una autoridad de registro (AR). Ésta confirma la identidad del usuario a la autoridad de certificación (AC), que a su vez emite el certificado. El usuario puede entonces firmar digitalmente un contrato utilizando su nuevo certificado. A continuación, la parte contratante comprueba su identidad ante una autoridad de validación (VA) que, a su vez, recibe información sobre los certificados emitidos por la autoridad de certificación.
