“…Although we notice that this attack is easy to carry out [16] and that there is no protection against it in current GPS receivers, it is possible to detect GPS spoofing attack by combining and analyzing location information gathered through both the GSM and the GPS networks. On mobile devices that do not provide the possibility to access a second source of location information (e.g., PDAs), several proposals have been made on how to fix this problem [4,10]. We hope that the next generation of GPS receivers will provide also authentication information to allow applications to recognize the level of trustworthiness of the signal (e.g., by using information about the time, noise level and strength's of the GPS signal, reported accelerations' sanity checks).…”

Abstract. Authenticating human users using public key cryptography provides a number of useful security properties, such as being able to authenticate to remote party without giving away a secret. However, in many scenarios, users need to authenticate from a number of client machines, of varying degrees of trustworthiness. In previous work, we proposed an approach to solving this problem by giving users portable devices which wirelessly issue temporary, limited-use proxy certificates to the clients. In this paper, we describe our complete prototype, enabling the use of proxy credentials issued from a mobile device to securely authenticate users to remote servers via a shared (or otherwise not trusted) device. In particular, our PorKI implementation combines out-of-band authentication (via 2D barcode images), standard Proxy Certificates, and platform attestation to provide usable and secure temporary credentials for web-based applications.

“…For access control decisions, we require the location of a mobile device to be verified such that a dishonest user cannot fake his or her location. Many such systems have been proposed, based on WiFi networks [3][4][5][6][7][8][9][10][11], GPS [8,[12][13][14][15][16], cellular telephone networks [13,15,[17][18][19], RFID [20] and other sensor networks [21][22][23].…”

Digital rights management allows information owners to control the use and dissemination of electronic documents via a machinereadable licence. This paper describes the design and implementation of a system for creating and enforcing licences containing location constraints that can be used to restrict access to sensitive documents to a defined area. Documents can be loaded onto a portable device and used in the approved areas, but cannot be used if the device moves to another area. Our contribution includes a taxonomy for access control in the presence of requests to perform non-instantaneous controlled actions.

“…This requires the devices and AP(s) to have tightly synchronized clocks allowing for detection of large tunnelling times of packages (temporal leash). Mundt defines a system that can be used with WLAN mesh networks to authenticate APs and prevent tunnelling or wormhole attacks in his paper [7]. In this system each AP is assumed capable of two-way communication and in possession of a public/private key-pair.…”

Location-based Digital Rights Management (DRM) refers to a system allowing the owner of an electronic file to specify not only the actions a user is allowed to perform regarding the content, but also restrict the actions to a specified geographical area. A method for retrieving location information is required. One such method is to place wireless accesspoints in areas of interest, requiring a device to be in the vicinity of the correct accesspoint(s) in order to access a file.
