NODE AND METHOD FOR SECURE SERVER COMMUNICATION

The present invention provides a node (100) which is suitable for allowing a client node to access a trusted service provided by another node in a network and comprises two units. The first unit (101) is configured to sign a certificate to certify the ownership of a public key, wherein the public key is owned by an enclave of a trusted execution environment, TEE, in the another node and a code to be executed for providing the trusted service to the client node is protected in the enclave. The second unit (102) is configured to make the signed certificate available to the client node. The certificate may be a certificate, which an enclave running in the another node provides to the node´s first unit (101) to demonstrate that it is an authentic part of a web domain (e.g. example.com) which a client node wants to securely access without risking to expose sensitive data to a man-in-the-middle purporting to be the trusted service.
