# Infraestructura de Confianza

Tres componentes clave conforman esta categoría de DPI:

1. **Firmas digitales o PKI:** Para garantizar que un documento/certificado/paquete de datos no ha sido manipulado, un país necesita generar la capacidad de adjuntar una firma digital verificable.
2. **Firma electrónica:** La capacidad de una persona o entidad para firmar electrónicamente un documento de forma digital (a través del móvil) para expresar su acuerdo.
3. **Consentimiento Granular:** La capacidad de una persona para dar su consentimiento de compartir datos para un propósito y un período de tiempo específicos con un tercero indicado, y generar un mecanismo de consentimiento auditable y firmado digitalmente para demostrar esa intención.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.cdpi.dev/es/technical-notes/infraestructura-de-confianza.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
