Limits in the Provable Security of ECDSA Signatures

ePrint Report: Limits in the Provable Security of ECDSA Signatures

Dominik Hartmann, Eike Kiltz

Digital Signatures are ubiquitous in modern computing. One of the most widely used digital signature schemes is ECDSA due to its use in TLS, various Blockchains such as Bitcoin and Etherum, and many other applications. Yet the formal analysis of ECDSA is comparatively sparse. In particular, all known security results for ECDSA rely on some idealized model such as the generic group model or the programmable …
