Abstract
The present application discloses a method of issuing pseudonymous authorisation tickets to nodes of a cooperative ITS, for signing messages, comprising: receiving a ticket request from a node in an authorisation server, and sending a validation request to an enrolment server, conducting a validity check in the enrolment server, and, when the validity check is passed, incrementing a counter value of a counter assigned to an account at an account server enrolled with the enrolment server for the requesting node, sending a validation message to the authorisation server, and issuing a pseudonymous authorisation ticket from the authorisation server to the requesting node, repeating the aforementioned steps until a predetermined charging period expires, and, upon expiry, sending, from the enrolment server to the authorisation server, said counter value, and sending a charging request calculated from said counter value from the authorisation server to the account server for charging said account.
