Analysis and Design of Identity Authentication for IoT Devices in the Blockchain Using Hashing and Digital Signature Algorithms

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.

Efficient Secure Computation from SM Series Cryptography

Wireless Communications and Mobile Computing, Volume 2023, Issue 1, 2023., 2023
The wireless network suffers from many security problems, and computation in a wireless network environment may fail to preserve privacy as well as correctness when the adversaries conduct attacks through backdoors, steganography, kleptography, etc. Secure computation ensures the execution security in such an environment, and compared with computation ...

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.

Characterization of Elliptic Curve Traces under FR-reduction [PDF]

, 2001
Elliptic curve cryptosystems([19],[25]) are based on the elliptic curve discrete logarithm problem(ECDLP). If elliptic curve cryptosystems avoid FR-reduction([11],[17]) and anomalous elliptic curve over F_q ([34],[3],[36]), then with current knowledge we
