NOMOP-ECDSA: A Lightweight ECDSA Engine for Internet of Things

Wireless Personal Communications, 2021
Internet of Things (IoT) has received attention recently, featuring tremendous applications. Due to the lack of authentication, popular IoT applications are prone to various attacks. However, because of resource limitation and heterogeneous characteristics of IoT applications, the cryptographic algorithms may fail to be universal adopted and thus, it ...

ECDSA weak randomness in Bitcoin

Future Generation Computer Systems, 2020
Abstract Bitcoin security draws more and more attention recently. One of Bitcoin vulnerabilities is caused by ECDSA weak randomness. A random number is not cryptographically secure, which leads to private key leakage and even fund theft. This security problem has been well known in Bitcoin community and fixed by applying RFC 6979 update in 2013.

One-More Unforgeability of Blind ECDSA

Lecture Notes in Computer Science, 2021
In this paper, we give the first formal security analysis on the one-more unforgeability of blind ECDSA. We start with giving a general attack on blind ECDSA, which is similar to the ROS attack on the blind Schnorr signature. We formulate the ECDSA-ROS problem to capture this attack.
