Abstract

In this paper we consider the (legal) representative in governmental ICT services and propose a secure private mail box system in which a message sent to the pupil is re-encrypted by the proxy server. This process enables the representative to decrypt the message. We also show its formal description of the protocols and evaluate the security by ProVerif model checking tool.
