“…Although smart phones are now very powerful and some PKI chips have already been developed for sensor nodes, it is still worthwhile to study how to reduce the number of slow and expensive private key operations [9]. Due to the regularity of human mobility [7], some sensor nodes and smart phones will encounter frequently.…”

Abstract. In this paper, a Shared Opportunistic Infrastructure (SOI) is proposed to reduce total cost of ownership for long-lived wireless sensor networks through exploiting human mobility. More specifically, various sensor nodes are opportunistically connected with their corresponding servers through smart phones carried by people in their daily life. In this paper, we will introduce the motivations, present the architecture, discuss the feasibility, and identify several research opportunities of SOI.

“…Unfortunately, hardware assist is considered necessary in XOM architecture to provide fast symmetric ciphers. SecFleck (Hu et al, 2009) which was mentioned earlier used external TPM chip on the sensor node. This TPM based public key platform facilitates message security services with confidentiality, authenticity and integrity.…”

“…Although the use of PKC in WSN is previously denied due to its high resourced (energy, memory and computational) (Yong et al, 2006), many recent works have proved its feasibility in the WSN area (Kocabas et al, 2008b). Latest, Wen Hu (Hu et al, 2009) used Trusted Platform Module hardware which is based on Public Key (PK) platform to augment the security of the sensor node. They claim that the SecFleck architecture provides internet level PK services with reasonable energy consumption and financial overhead.…”

“…Therefore there is a need to adequately protect the keys to ensure confidentiality and integrity of sensitive data. While majority of the work done in WSN security have focused on the security of the network (Hu et al, 2009), our proposed works will consider the three challenges describe earlier to secure the WSNs applications from software and physical types of attacks. Beside we will also ensure smallest security parameter in our overall security design.…”

“…The goal of these protocols is to verify the trustworthiness of resource-constrained systems, without requiring dedicated tamper-resistant hardware or physical access to the device. Attestation based on tamper-resistant hardware [12], though effective [17], is not yet viable on low-cost commodity embedded devices. Furthermore, hardware attestation techniques, while having stronger security properties, ultimately rely on a per-device TPM and the availability of a trusted BIOS that begins attestation at boot time.…”

Abstract. Remote attestation is the process of verifying internal state of a remote embedded device. It is an important component of many security protocols and applications. Although previously proposed remote attestation techniques assisted by specialized secure hardware are effective, they not yet viable for low-cost embedded devices. One notable alternative is software-based attestation, that is both less costly and more efficient. However, recent results identified weaknesses in some proposed software-based methods, thus showing that security of remote software attestation remains a challenge. Inspired by these developments, this paper explores an approach that relies neither on secure hardware nor on tight timing constraints typical of software-based technqiques. By taking advantage of the bounded memory/storage model of low-cost embedded devices and assuming a small amount of read-only memory (ROM), our approach involves a new primitive -Proofs of Secure Erasure (PoSE-s). We also show that, even though it is effective and provably secure, PoSE-based attestation is not cheap. However, it is particularly well-suited and practical for two other related tasks: secure code update and secure memory/storage erasure. We consider several flavors of PoSE-based protocols and demonstrate their feasibility in the context of existing commodity embedded devices.
