A suite of efficient authentication and key establishment protocols for securing contact or contactless interfaces between communicating systems. The protocols may be used in secure physical access, logical access and/or transportation applications, among other implementations. The system authenticates a mobile device such as a smart card and/or mobile phone equipped with a secure element presented to one or more host terminals and establishes shared secure messaging keys to protect communications between the device and terminal. Secure messaging provides an end-to-end protected path of digital documents or transactions through the interface. The protocols provide that the device does not reveal identification information to entities different from a trusted host. The terminal may be a contactless reader at a door for controlling physical access, a desktop, laptop or kiosk for controlling logical access, and/or an access point for obtaining an encrypted digital ticket from an authenticated mobile device used for transit applications. |
