Complexity of ECDLP under the First Fall Degree Assumption. [PDF]
IACR Cryptol. ePrint Arch., 2015 Semaev shows that under the first fall degree assumption, the complexity of ECDLP over $\bF_{2^n}$, where $n$ is the input size, is $O(2^{n^{1/2+o(1)}})$. In his manuscript, the cost for solving equations system is $O((nm)^{4w})$, where $m$ ($2 \le m \le

PRIME POINTS ON ELLIPTIC CURVES AND ITS IMPACT ON ECDLP.
IACR Cryptol. ePrint Arch., 2007 In this paper we present that some statistical properties of points on elliptic curve can be used to form new equivalence classes. This can have an impact on solving discrete logarithm (ECDLP) owing to the reduction of the number of points among which a ...

SPRA: Scalable policy‐based regulatory architecture for blockchain transactions
IET Blockchain, Volume 3, Issue 4, Page 265-282, December 2023., 2023 Most of the current regulatory schemes for blockchain transactions are customized for specific blockchain applications and lack generality and scalability. To address these problems, this paper proposes a scalable policy‐based layered blockchain transaction regulation architecture (SPRA), and also designs a regulatory policy description language (XRPL)

A Lightweight Three‐Party Mutual Authentication Protocol for Internet of Health Things Systems
Journal of Healthcare Engineering, Volume 2023, Issue 1, 2023., 2023 In Internet of Health Things (IoHT) systems, there is a two‐hop network structure between the authentication server TA, Internet of Things Connector (IotC), and wearable sensor (WS). Attackers can use the sensor layer network (the first hop) between the IotC and WS to steal patient’s health‐related information and undermine the security of the system ...

Security and Communication Networks, Volume 2023, Issue 1, 2023., 2023 With the advancement in information and communication technology (ICT), secure farm‐to‐home communication has become an emerging concept. Food is the most basic essential commodity for the survival of human beings which is produced by farmers. However, because of the presence of intermediaries, farmers/producers do not make a sufficient profit and also

Security and Communication Networks, Volume 2023, Issue 1, 2023., 2023 At the moment, digital documents are just as important as paper documents. As a result, authenticity is essential, especially in legal situations and digital forensics. As technology advances, these digital signature algorithms become weaker, necessitating the development of digital authentication schemes capable of withstanding current security ...

International Journal of Distributed Sensor Networks, Volume 2023, Issue 1, 2023., 2023 This paper proposes a blockchain‐based identity authentication (BA) scheme for IoT devices to solve the authentication security problem of IoT devices. The BA scheme uses hashing and digital signature algorithms to achieve integrity and nonrepudiation of authentication messages.
