“…JavaCard [1], [28] is a standard that defines an operating environment, a subset of the Java programming language, and limited Java libraries that allow the development, deployment, and execution of applications on a JavaCard-enabled HSM. It provides abstraction and sandboxing mechanisms, via a Java virtual machine on the HSM, where multiple applications (named applets) independently of each other on the HSM.…”

E-mail: [scheid,killer,franco,rodrigues,stiller]@ifi.uzh.ch [andreas.knecht2,tim.strasser]@uzh.ch the device's private key is not secured or it is leaked [9], a malicious actor can generate or modify transactions, rendering the cold chain measurements untrusted. This problem of private key management becomes evident as well, when considering highly-constrained IoT devices (i.e., Class 0 IoT devices [4]) that cannot directly interact with a BC node using standard Internet protocols (e.g., HTTP) or have power limitations (e.g., batteries). Thus, relying on low power communication (e.g., Bluetooth Low Energy, BLE) between edge nodes signing transactions and handling key management are possible in a hybrid approach [33]. Such an edge node is a single point of failure and, as it stores all the devices' private keys, if compromised, all devices communicating with that edge nodes are compromised as well. It is crucial that all devices' private keys are secured, meaning that they cannot leave the device for transaction signing, and devices are to be physically secured against tampering.

“…Subscription could be implemented by encrypting each data set, and using smart cards for decryption. The IBM Java Card [14] for example has a rich set of built-in cryptographic functions and can act as a tamperproof key for decrypting received data sets. The service provider primes the card with secret keys, one set for each service subscribed to, and sells it to the client.…”

An interesting trend in the continuing convergence of information technologies is the emergence of the Internet as a content provider in its own right, as opposed to its simply being one of many delivery channels. For example, it is increasingly the primary source for items such as court rulings and software releases. Unfortunately the IP protocols normally employed for reliable data transfer are of the point-to-point type and not well suited to large-scale one-to-many dissemination. Sudden rushes to obtain new items can cause severe traffic congestion and degrade network service across a whole region. Even worse, sites which are routinely popular cause routine congestion. Broadcast technologies should be able to provide a better solution in terms of scalability. The Internet has a mature protocol suite for IP multicast and more recently the traditional wireless broadcast industry has started moving from analog to digital transmission formats. However, in both these cases the emphasis in protocol development has been on support for continuous media, which requires timeliness of delivery rather than bit-perfect data integrity. A further problem with the new digital broadcast channels is their lack of support for integration with the Internet. This paper examines some of the issues involved in providing both reliable and scalable dissemination across broadcast channels and describes the DABWeb architecture for Internet content dissemination via digital broadcast.1 The original WebTV product (1995) was a set-top box with no local storage, which connected to the Internet by a phone line. It involved Sony and Philips (end-system integrators); Excite (WWW search engine), Surfwatch (WWW filter); Concentric (ISP); IDT (electronics); Headspace(ambient music); and Progressive (audio/IP specialists). The company was bought by Microsoft at some point, and is now a brand name for a wider range of services and products.

Abstract. This paper explores computer security in pervasive computing with focus on user authentication. We present the concept of Proximity-Based User Authentication, as a usability-wise ideal for UbiComp systems. We present a context-aware user authentication protocol, which (1) uses a JavaCard for identification and cryptographic calculations, (2) uses a context-awareness system for verifying the user's location, and (3) implements a security fall-back strategy. We analyze the security of this protocol and discuss the tradeoff between usability and security. We also present our current implementation of the protocol and discuss future work.
