ECDSA
A digital signature algorithm based on elliptic-curve cryptography, widely used for identity authentication and data integrity verification. It is highly sensitive to the quality of random numbers; reuse or predictability of nonces can lead to private key compromise.
Timeline (last 90 days)
PQC signatures are typically an order of magnitude larger than ECDSA signatures, which has an impact on on-chain storage and transaction throughput.
ECDSA is currently the most common ECC signature scheme and is widely supported by mainstream CAs and CDNs such as Let's Encrypt and Cloudflare.
The digital signature mechanism for US driver's license barcodes is typically implemented based on the Elliptic Curve Digital Signature Algorithm (ECDSA).
ECDSA is relatively strong in security when implemented correctly, but is extremely sensitive to the quality of the random number k; if k is reused or is predictable, an attacker can recover the private key from a small number of signature samples.
The leak of Sony PlayStation 3's firmware signing key originated from engineers using a fixed k value, and researchers needed only two signatures to recover the private key.
