Protection of privacy in wireless telecommunication networks

Abstract

A method of protecting the exchange of privacy-sensitive data in a wireless communication network, the method including generating and providing a public cryptographic key to a first entity, possessing the data to be sent to the network through a wireless connection; generating and providing a private secret cryptographic key to a second entity, being the intended recipient of the data, the private key being bound to the public key and being associated to privacy support context information to identify the network; having the network send to the first entity respective wireless network privacy support context information; having the first entity receive the information and encrypt the data using the public key and the received information to obtain protected, encrypted privacy-sensitive data; having the first entity send to the second entity through the network the encrypted data; and having the second entity decrypt the encrypted data exploiting the private key.
