The TS@ is an authority of time-stamping provision of all public administrations with the aim of offering services of sealed, validation and resealed seals of time.

The TS@ services are available free of charge for those public administrations who request it. The service is provided through the network SARA (Administrative Intranet), so to use it is necessary to be connected to the network.

Agreements have been signed with all the autonomous communities to allow the use of TS@ services applications electronic administrations they so wish. In the case of local entities, some Autonomous Communities included in the convention the possibility of accessing TS@ services via accessions.

Así mismo pueden utilizar el servicio las Universidades, a través de la CRUE y Red Iris.

La forma más común de uso de la TS@ es modo servicio. Este modo consiste en que la plataforma TS@ del MPTFP proporciona servicios de sellado, validación y resellado de sellos de tiempo,  a través de servicios web o el interfaz RFC. Las aplicaciones que desean utilizar los servicios de TS@, se conectan mediante la red SARA a los servicios de TS@ del MPTFP. Es el modo recomendado para aquellos organismos con un volumen mensual de peticiones medio/bajo. El MPTFP proporciona una plataforma igual al a de producción para que los organismos que deseen usar los servicios de TS@ realicen pruebas, y un servicio de soporte para gestionar las altas e integraciones.

There is another way to use of TS@, the federal model. This Only recommended for those agencies with a volume of transactions very high. The MPTFP provides the TS@ software, so that the agency install it and administered in its dependencies. In this case the deployment, installation and administration is the responsibility of the agency. The MPTFP will provide updates and patches of software according to be generated.

You can consult the available services or model Province through the FAQ.

The MPTFP provides a support service as support for the integration of computer applications that go to make use of the services of validating @firma in different government agencies. Within this support, MPTFP provides a platform of evidence, which can use public agencies during the integration of their applications.

For testing services provided by the TS@ MPTFP, it is not necessary to hold any act of commitment by any of the parties, and without any cost.

Para poder realizar peticiones a los servicios proporcionados por la plataforma de validación, se han de cumplir los siguientes puntos:

  1. Use of the Intranet Administrative: Requests may only be performed from machines connected to the Administrative Intranet (SARA network) and with access permissions on the platform. Therefore be identified those machines from which you are going to perform the tests and request TS@ support ( Access the form ) permiso de acceso a las IPs internas de dichas máquinas.
  2. This will complete the corresponding file with the same information and send it to support for its high TS@ effective. You can download the form of the Download area of the website of the TS@, on the portal of electronic administration ( ). To access documentation is required to be registered in the portal and access it from the Administrative Intranet (SARA network).
  3. Identification of applications: In order to monitor the activity of applications and the platform (both in evidence as in production), requests should be conducted by applications identified through certificate or username and password on the platform.
  4. Crear un cliente: Una vez que se dispongan de permisos es necesario desarrollar  un Cliente para que realice la petición a los servicios publicados en la plataforma.
  5. To develop the client, provides integrators to the description of the web service stations. For this, the platform specifies for each Web Service (hereinafter TRABAJAR) the file WSDL which includes the URL of WS, the message of the request with the XML schema of entry and the Reply message returned by the service. This information is provided in the Download area of the website of the TS@, on the portal of electronic administration ( ), en la zona restringida para usuarios registrados. Además de los WSDL Y XML se proporcionan varios clientes de ejemplo desarrollados en Java. También disponen de la posibilidad de realizar peticiones RFC.


To use the platform TS@ must meet a number of prerequisites, which we list below:

  • For accessing needed have given the application of high in the platform, together with its certificate in case of use authentication certificate or through user password. Once you have your access data may access services registered for its implementation. To create an application shall perform the following steps:
    1. Ponerse en contacto con el servicio de soporte (CAU) de @firma, indicando el Organismo (Ministerio, Comunidad Autónoma o Entidad Local) que desea integrarse en el servicio, así como los datos de contacto del mismo:
    Contact form
    2. El servicio de soporte CAU se pondrá en contacto con el Organismo para informar de los prerrequisitos que son necesarios para iniciar la integración. Una vez informados los prerrequisitos, el servicio de Soporte (CAU) le proporciona al Organismo la documentación de bienvenida, que se compone de:
    a. ACL (form to access control).
    b. Documentation
    (c. Services of TS@.
    d. Manual to integrate the client of the TS@.
    3. El Organismo debe devolver el ACL debidamente cumplimentado al servicio de Soporte (CAU) para finalizar el proceso de integración.
  • Another thing to bear in mind is that the access to these services is done via the network SARA. It Is an intranet of public administrations which you must connect through his Ministry, Autonomous community or Local Entity, for which should contact them (ultimately IPs closed). It is desirable processing in advance such access. Meanwhile, can be done in a controlled trials development environment enabled the effect from the Internet (this environment is similar to the right, with the same configurations, services, certificates admitted,... that in production).

The ACL (access Control list) is a model of data request access and use of the services of the TSA (EXCEL form). It contains a number of data required for the integration of the Agency in TSA. Below, explains the various fields of the form:

  • Dataset "data to fill": you must indicate the IP from which you access to services the TS@ and data of a person/communications systems with which can contact you in case of any problems of connectivity, as well as indicate the protocols of communication to be used.
  • Dataset "data to fill (only if it is used WS)": in case of request access via WS, it has to inform the following data:
    or format of the signature of Respuesta.- signature format with which you want the strong platform messages of response to their requests for service.
    or method of autorización.- method with which to authenticate your messages to petition of service to the platform TS@. It is recommended with certificate.
    o Cifrar mensajes SOAP.- Indica si se desea cifrar el SOAP remitido mediante una clave simétrica. En caso afirmativo, ésta ha de ser indicada en este punto.
  • Conjunto de datos "Datos a rellenar (Sólo si se usa RFC 3161 sobre SSL autenticado)" y Conjunto de datos "Datos a rellenar (Sólo si se usa RFC 3161 sobre HTTPS)": Si se solicita el acceso mediante uno de estos protocolos, ha de indicarse el certificado con el que se autenticarán en cada caso.
  • Dataset “ data to fill out by the agency ”:
    or set of data "Environment": Bring the environment to which you want to access (Development, production or both).
    o Conjunto de datos "Aplicación" : Hay que indicar el nombre de la aplicación a dar de alta, una breve descripción de la aplicación y Organismo (Ministerio y Dirección General, Comunidad Autónoma o Entidad Local) para el que se está desarrollando la aplicación. Los datos de la persona responsable de la aplicación, con quien nos pondremos en contacto en caso notificaciones al respecto de la misma. Breve descripción de los servicios telemáticos que soportará la aplicación y URL donde se ubicará la misma.

There are two environments TS@ platform: one of development for the testing, and one of production, which correspond to the real environment of the platform.

Las url de acceso a para la realización de peticiones según protocolo se encuentran a continuación. A los protocolos RFC y RFC+SSL se les ha podido cambiar los puertos de despliegue mediante la herramienta de administración, y según el punto de origen desde donde se lancen son:

  • Petitions HTTPS:
    https :// XXX.XXX.XXX.XXX:8443/tsamap/TspHttpServer

Still XXX.XXX.XXX.XXX the URL of access to the services offered by the TSA that, depending on the environment access, this may take the following values:

  • URL access to TSA development environment:
    - DNS Name (SARA Network):
  • URL access to TSA PRODUCCIÓN environment:
    - DNS Name (SARA Network):

Service requests made through web services (Web Services - WS) must be conducted by the ports 80 (http) AND 443 (https). Requests for time-stamping RFC through the HTTPS are directed to the port 8443.

You can get this document in the "Download Area" “ platform of time-stamping TS@ ” in subparagraph "high document application and IP".

Puede encontrar toda la información sobre la TS@ en la iniciativa del PAe creada a tal efecto. En el área de descargas de dicha iniciativa pueden encontrar la documentación de los servicios así como los ejemplos de integración.

To access the complete documentation must be a registered user in the portal PAe, as well as accessing the Administrative Intranet portal (SARA Network).
