TECHNIQUE FOR COMMUNICATION BETWEEN AN APPLICATION IMPLEMENTING A SERVICE AND A SERVER

摘要

The invention relates to a method for communication between an application implementing a service run on a user device (10) and a main server (20). When an attempt is made to establish a first secure communication, the compliance of a public key certificate sent by the main server is checked against a reference certificate for the main server, the establishment of secure communication being conditional upon said compliance check. If the public key certificate sent by the main server is not compliant, a second secure communication is established with an update server (21), and a public key certificate sent by the update server is checked for compliance against a reference certificate for said update server. Once the second secure communication has been established, an updated reference certificate for the main server is received, said updated certificate being intended to be used by the client application the next time secure communication is established with the main server.
