This paper presents a new concept, called tandem, dedicated to smart cards that control TLS-based applications. The originality of this approach is to introduce a collaborative process between a smart card and its docking host. This technology enables the secure downloading of a huge amount of data, in untrustworthy computers. We present software paradigms(More)
In this paper we present a new cooperative architecture that aims at sharing services managed by secure elements. Smartphones such as Android mobiles include IP resources and support several kinds of secure elements (SIM module, removable SD memory, external NFC smartcard...). These devices typically host payment or access control services. Because users(More)
This paper introduces a new model dedicated to the Internet of Thing that interacts with active RFIDs. Instead of targeting IP stacks implementation in tags, we plan to support the Host Identity Protocol, which dissociates IP address and host location and that has been recently defined by the Internet Engineering Task Force (IETF). We propose an(More)
The increase of authenticating solutions based on RADIUS servers questions the complexity of their administration whose security and confidentiality are often at fault especially within Cloud Computing architectures. More specifically, it raises the concern of server administration in a secure environment for both the granting access’ company and(More)

This paper presents a new secure model for NFC (Near Field Communication) services based on the P2P (Peer to Peer) mode. NFC is a proximity communication technology more and more supported by smartphones or consumer devices that seems a promising technology for the Internet of Things (IoT). It is used in applications such as payment, access control,(More)

This demonstration presents a new and innovative open platform whose goal is to enable secure mobile applications. Secure Elements (SE) are hosted in dedicated servers, whose protocol (RACS) is detailed by an IETF draft. They are remotely used from mobiles via secure TLS channels. These channels are booted from TLS NFC (Near Field Communication) smartcards(More)
