According to the legislation of each country, the CAs receive different names, e.g.: Trust Services Provider (UE), Certification Entity of Information and Related Services (Ecuador) or Digital Certification Services Provider (Peru)… Regardless of the denomination agreed in each country, the functions in the provision of these services are common in all countries, having as a basic guide the UNCITRAL Model Law on Electronic Signatures (UNCITRAL is the main legal body of the United Nations).
Another essential element, common in all international legislation, is the consideration that the identity outlined in the electronic certificate is legal evidence, and that electronic signatures made with these certificates have, regarding the data recorded electronically, the same Legal value that the handwritten signature in relation to those consigned on paper.
