“…In case of there has no pairwise key between two neighboring sensors in the original random key scheme, an MCS can help to establish a pairwise key of two neighboring sensors to improve the probability of connectivity. Motivated by a recently published group key distribution scheme by Harn et al in 2020 [20], we propose two key distribution schemes, one with confidentiality only and the other with both confidentiality and authenticity. Since the computations involved are logical Exclusive-OR (XOR) operations, they are both lightweight schemes.…”

Sensitive data collected by a wireless sensor network (WSN) should be protected by a secret key shared between two adjacent (or neighboring) sensors. Sensors are mobile devices with limited memory and computational power, and sensors are deployed in a field randomly in which relative positions among sensors cannot be pre-determined. Key distribution in WSN is a challenging research problem. Random key distribution is one of the most popular key distribution techniques in WSN; but it is a probabilistic key distribution scheme since two neighboring sensors may or may not share any pairwise key. There are many published papers to improve the probability of connectivity of two neighboring sensors. In this paper, a novel design of lightweight key establishment is proposed based on top of random key distribution. The first scheme can increase the probability of connectivity of two neighboring sensors, and the second scheme can also enable sensors to authenticate the established pairwise key. Both schemes need only XOR operation so they are lightweight and especially suitable for WSNs.

“…Two papers recently published by Harn et al [6,7] propose some very simple key distribution schemes designed to enable two or more parties to establish a shared secret key with the aid of a third party. Unfortunately, as we show, most of the schemes are inherently insecure and all are incompletely specified.…”

“…Section 2 provides an introduction to the protocols in question, and sets them in the context of the extensive prior art. This is followed by analyses of the various proposed protocols: Sections 3, 4, 5 and 6 provide analyses of the four protocols in the first paper [7], and Section 7 briefly examines the almost identical protocols in the second paper [6]. Finally, Section 8 concludes the paper.…”

“…The two papers, whilst having very closely-related content and the same set of authors, do not refer to each other, and it is hard to know which was submitted first. For simplicity we refer throughout to Paper A [7], and Paper B [6]. Since the two schemes in Paper B [6] both appear to be slightly elaborated versions of two of the schemes in Paper A [7], we consider Paper A first.…”

For secure communication in a distributed cooperation, generally, the data are encrypted and decrypted using a symmetric key. The process of creating, distributing, storing, deploying, and finally revoking the cryptographic keys is called key management. On the basis of the structure, usability, and complexity of the cyber‐physical systems, each one of the current key management practices is suitable for a specific range of applications. However, these schemes have some drawbacks in common, such as complicated key generation and distribution process, using key storage, attacks, and traffic load. This paper proposes a key management model for establishing secure communications in the distributed industrial intelligent systems. The model is attack resistant, has high usability in real‐world applications, and transforms the current customary key management workflow to enhance security and reduce weaknesses. Its main features include reduced process, intelligent attack resistance, producing dynamic keys with no additional cost, and eliminating key storage and revocation calls.
