URQUIJO MORALES, Yanssel  e  ORELLANA GARCIA, Arturo. PKI-based trust scheme for the exchange of electronic clinical information in the XAVIA HIS system. RCIM [online]. 2020, vol.12, n.2  Epub 01-Dez-2020. ISSN 1684-1859.

Computer security has become a necessity and a right for all citizens. The IT systems used in the health sector have much easier and more sustainable digital storage and guarantee the privacy and integrity of information, which are sensitive issues. In Cuba, there is no centralized PKI (Public Key Infrastructure) scheme at the national level that promotes and guarantees the security of sensitive information in the public health system, which puts the authenticity, integrity and confidentiality of personal medical data at risk.

The aim of our work was to design a security structure centered on PKI among health institutions, based on the national public key infrastructure as root certificate authority (CA). In order to achieve this, a documentary analysis was carried out on the current state of the art in the subject; as well as interviews with administrative staff, hospital managers and specialists in computer security, which allowed the research bases to be created.

As a result, a trust scheme was obtained that promotes the secure exchange of patients' medical records between health institutions. The implementation of a PKI infrastructure in the health sector allows institutions to exchange medical records through a network with a high level of security.
