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.

The order elliptic curves over finite fields of characteristic two using the Schoof algorithm [PDF]

, 2007
The elliptic curve cryptosystem is a popular cryptosystem. Its safety depends on the difficulty of the elliptic curve discrete logarithm problem (ECDLP). From the viewpoint of ECDLP, it is very interesting to determine the order of elliptic curves.
