“…We used mainly C code and some assembly language to speed up our time critical arithmetic routines (in particular binary polynomial multiplication). On our most constrained 8-bit MICAz device we were able to compute the pairing in 2.66s -a time comparable with the scalar point multiplication operation presented in [21]. The whole key agreement takes as little as 0.1s on Imote2 and 4.27s in the worst case on the most constrained mote.…”

Abstract-Despite much research effort key distribution in Wireless Sensor Networks (WSNs) still remains an open problem. In this paper we address this issue by proposing a simple identitybased key agreement scheme. Our protocol uses Identity-Based Cryptography (IBC) and secret key pre-distribution. We argue that IBC is in many ways a perfect solution for WSNs. It reduces the number of required keys, simplifying the key management in the network, and has a lower communications overhead than traditional public key protocols.We evaluate our proposal on a broad range of sensor platforms to show its efficiency on different CPU architectures. A complete key agreement procedure takes less than 3s on a resourceconstrained Tmote Sky node without requiring any communication between two parties. To our knowledge this work is the first practical implementation of a complete IBC scheme on sensor devices.We identify a range of WSN applications which would benefit from the incorporation of a security architecture, and show that the scheme described here makes it feasible to deploy these applications in the real world.

“…Most schemes provide encrypting capabilities based on a secret key shared among nodes, either in software [43] or hardware level [44], [45]. In addition, notable advances have been observed in the implementation of Elliptic Curve Cryptography (ECC) [46], [47], which has emerged as a promising alternative to RSA-based algorithms, guaranteeing the same level of security, 18 while employing a much smaller key size. To overcome the limitations of traditional symmetric cryptography in wireless networks, biometrics [48], [49] exploit particular physiological values of the patient's body in order to provide efficient cryptographic techniques in WBANs, thus gaining significant ground in healthcare environments.…”

The emerging technology of Machine-to-Machine (M2M) communications is bringing a paradigm shift in healthcare delivery. A broad range of e-Health applications can be conceived, with considerable benefits for both patients and healthcare providers. Many technological challenges have to be met, however, to ensure the widespread adoption of e-Health solutions in the future. In this context, we aim to provide a comprehensive overview on M2M systems for e-Health applications from a wireless communication perspective. We provide an overview of the candidate wireless technologies that are suitable for different parts of the M2M system architecture and then show how these technologies are seamlessly integrated to provide an end-to-end e-Health solution. In particular, we discuss end-toend solution designs and testbed implementations, we present the key security and privacy challenges associated with the sensitive nature of medical data and we summarize the most recent research projects dedicated to e-Health applications.

Abstract-Key distribution in Wireless Sensor Networks (WSNs) is challenging. Symmetric cryptosystems can perform it efficiently, but they often do not provide a perfect trade-off between resilience and storage. Further, even though conventional public key and elliptic curve cryptosystems are computationally feasible on sensor nodes, protocols based on them are not. They require exchange and storage of large keys and certificates, which is expensive. Using Pairing-based Cryptography (PBC) protocols, conversely, parties can agree on keys without any interaction. In this work, we (i) show how security in WSNs can be bootstrapped using an authenticated identitybased non-interactive protocol and (ii) present TinyPBC, to our knowledge, the most efficient implementation of PBC primitives for an 8-bit processor. TinyPBC is able to compute pairings in about 5.5s on an ATmega128L clocked at 7.3828-MHz (the MICA2 and MICAZ node microcontroller).
