Efficient and Provably Secure Key Agreement for Modern Smart Metering CommunicationsKey Agreement • October 18th, 2018
Abstract: Security in modern smart metering communications and in smart grid networks has been an area of interest recently. In this field, identity-based mutual authentication including credential privacy without active involvement of a trusted third party is an important building block for smart grid technology. Recently, several schemes have been proposed for the smart grid with various security features (e.g., mutual authentication and key agreement). Moreover, these schemes are said to offer session key security under the widely accepted Canetti-Krawczyk (CK) security model. Instead, we argue that all of them are still vulnerable under the CK model. To remedy the problem, we present a new provably secure key agreement model for smart metering communications. The proposed model preserves the security features and provides more resistance against a denial of service attack. Moreover, our scheme is pairing-free, resulting in highly efficient computational and communication efforts.

Key agreement in peer-to-peer wireless networksKey Agreement • August 30th, 2005
Abstract— We present a set of simple techniques for key establishment over a radio link in peer-to-peer networks. Our approach is based on the Diffie-Hellman key agreement protocol, which is known to be vulnerable to the “man-in-the-middle” attack if the two users involved in the protocol do not share any authenticated information about each other (e.g., public keys, certificates, passwords, shared keys, etc.) prior to the protocol execution. In this paper, we solve the problem by leveraging on the natural ability of users to authenticate each other by visual and verbal contact. We propose three techniques: the first is based on visual comparison of short strings, the second on distance bounding, and the third on integrity codes; in each case, the users do not need to enter any password or other data, nor do they need physical or infrared connectivity between their devices. We base our analysis on a well-established methodology that leads us to a rigorous modularization and a thorough
EKG-based Key Agreement in Body Sensor NetworksKey Agreement • May 15th, 2008
Abstract—Preserving a person’s privacy in an efficient manner is very important for critical, life-saving infrastructures like Body Sensor Networks (BSN). This paper presents a novel key agreement scheme which allows two sensors in a BSN to agree to a common key generated using electrocardiogram (EKG) signals. This EKG-based Key Agreement (EKA) scheme aims to bring the “plug-n-play” paradigm to BSN security whereby simply deploying sensors on the subject can enable secure communication, without requiring any form of initialization such as pre-deployment. Analysis of the scheme based on real EKG data (obtained from MIT PhysioBank database) shows that keys resulting from EKA are: random, time variant, can be generated based on short-duration EKG measurements, identical for a given subject and different for separate individuals.

Practical Supersingular Isogeny Group Key AgreementKey Agreement • March 27th, 2019
In this section, we present the implementation detail of the supersingular isogeny group key agreement protocol in the case of three parties. The parties compute different large-degree isogenies over different torsion subgroups of a supersingular elliptic curve to efficiently establish a shared secret key. Our software is publicly available4 for evaluation and reproducibility.
Haffner Energy and IðunnH2 sign a key agreement to reduce costs and secure carbon supply for Iceland’s largest e-SAF projectKey Agreement • September 2nd, 2024
E-SAF, which is projected to account for half of total SAF production by 2050 in Europe, is made from combining green hydrogen with recycled carbon, ideally from a biogenic source. Biogenic carbon typically comes in the form of biogenic CO2, a costly gas to capture, transport, and store. This cost issue is typically compounded by the challenge facing many large-scale hydrogen and e-fuel projects: they are often located in areas with good access to renewable power, but limited access to biogenic carbon, as is the case in Iceland.

Key Agreement from Close Secrets over Unsecured ChannelsKey Agreement • May 22nd, 2009
We consider information-theoretic key agreement between two parties sharing somewhat different versions of a secret w that has relatively little entropy. Such key agreement, also known as information reconciliation and privacy amplification over unsecured channels, was shown to be theoretically feasible by Renner and Wolf (Eurocrypt 2004), although no protocol that runs in polynomial time was described. We propose a protocol that is not only polynomial-time, but actually practical, requiring only a few seconds on consumer-grade computers.

An Interval-based Contributory Key AgreementKey Agreement • September 10th, 2011
Applications in Dynamic Peer Group are becoming in- creasing popular nowadays. There is a need for security services to provide group-oriented communication privacy and data integrity. It is important that members of the group can establish a common secret key for encrypting group communication. A secure distributed group key agreement and authentication protocol is required to han- dle this issue. A key tree approach has been proposed by other authors to distribute group key in such a way that the rekeying cost scales with the logarithm of the group size for a join or leave request. The efficiency of this key tree approach critically depends on whether the key tree remains balanced over time as members join or leave. Instead of performing individual re-keying operations, an interval-based approach of re-keying is adopted in the pro- posed scheme. The proposed interval based algorithms considered are Batch algorithm and the Queue-batch al- gorithm. The interval-based approach provides
