This paper proposes a novel architecture that offers features for a truly interactive yet private document archival cloud. The proposed secure document archival system has been specifically designed for the elimination of paper based systems in organization. The architecture attempts to shift paper based systems to an electronic archival system where the documents are secure and the system is supportive to user demands and features. Therefore besides document archival the proposed architecture also offers the authentication and encryption for secure keeping of data on the cloud. We propose a novel combination of SSL coupled with ICMetrics for the document archival system, which will prove to be a very valuable tool for encrypting and authenticating in the cloud world.

“…After each ICMetric key generation stage the produced ICMetric key [13] is temporary and exists only locally, and the reproduction of the ICMetric key once again takes place from measurable characteristics of the integrated circuit [10]. The ICMetric key is generated each time it is requested for identification or encryption functions.…”

A Scheme for the Generation of Strong ICMetrics Based Session Key Pairs for Secure Embedded System Applications

2013 27th International Conference on Advanced Information Networking and Applications Workshops

et al. 2013

This paper presents a scheme for the generation of strong session based ICMetrics key pairs for security critical embedded system applications. ICMetrics generates the security attributes of the sensor node based on measurable hardware and software characteristics of the integrated circuit. In the proposed scheme a random session ID is assigned by a trusted party to each participating network entity, which remains valid for a communication session. Our work is based on the design of a key derivation function that uses an ICMetrics secret key and a session token assigned by the trusted party to derive strong cryptographic key pairs for each entity. These session tokens also serve the purpose of identification/authentication between the trusted parties and the respective nodes in each network. The main strength of our proposed scheme rests on the randomness feature incorporated via the random session ID's, which makes the generated strong private/public key pair highly resistant against exhaustive search and rainbow table attacks. Our proposed approach makes use of key stretching using random session tokens via SHA-2 and performs multiple itertions of the proposed key derivation function to generate strong high entropy session key pairs of sufficient length. The randomness of the assigned ID's and the session based communication hinders the attacker's ability to launch various sorts of cryptanalytic attacks, thereby making the generated keys very high in entropy. The randomness feature has also been very carefully tuned according to the construction principles of ICMetrics, so that it doesn't affect the original ICMetrics data. The second part of the proposed scheme generates a corresponding public session key by computing the Hermite Normal Form of the high entropy private session key.

“…Analogous to biometrics, the features extracted from integrated circuits might not be stable, in that case the feature values may be based on values taken from a Gaussian distribution [13].…”

Improving Resilience Against Node Capture Attacks in Wireless Sensor Networks Using ICmetrics

Wireless Sensor Networks (WSNs) have the potential of being employed in a variety of applications ranging from battlefield surveillance to everyday applications such as smart homes and patient monitoring. Security is a major challenge that all applications based on WSNs are facing nowadays. Firstly, due to the wireless nature of WSNs, and secondly due to their ability to operate in unattended environments makes them even more vulnerable to various sorts of attacks. Among these attacks is node capture attack in WSNs, whose threat severity can range from a single node being compromised in the network to the whole network being compromised as a result of that single node compromise. In this paper, we propose the use of ICMetric technology to provide resilience against node compromise in WSN. ICmetrics generates the security attributes of the sensor node based on measurable hardware and software characteristics of the integrated circuit. These properties of ICmetrics can help safeguard WSNs from various node capture attacks.
