Quantum resource estimates for computing elliptic curve discrete logarithms [PDF]

, 2017
We give precise quantum resource estimates for Shor's algorithm to compute discrete logarithms on elliptic curves over prime fields. The estimates are derived from a simulation of a Toffoli gate network for controlled elliptic curve point addition ...

Securing Topology Control in SDWSNs Using Identity‐Based Cryptography

Journal of Sensors, Volume 2023, Issue 1, 2023., 2023
In software‐defined wireless sensor networks (SDWSNs), topology control is a fundamental procedure to maintain the global network topology. However, the open wireless channels of SDWSNs make it possible for an attacker to eavesdrop, replay, or modify the topology messages, thus posing a great threat to the network operations.

An Efficient Pairing‐Free Certificateless Signature Scheme with KGC Trust Level 3 for Wireless Sensor Network

Wireless Communications and Mobile Computing, Volume 2023, Issue 1, 2023., 2023
With the widespread adoption of wireless sensor networks (WSN), the security of the WSN has been a wide concern. Certificateless signature eliminates the certificate management problem and key escrow problem and is considered a feasible solution to solve the data integrity and authentication of WSN. Recently, Thumbur et al.
