ePrint Report: Security Analysis of Signature Schemes with Key Blinding

Edward Eaton, Tancrède Lepoint, Christopher A. Wood

Digital signatures are fundamental components of public key cryptography. They allow a signer to generate verifiable and unforgeable proofs---signatures---over arbitrary messages with a private key, and allow recipients to verify the proofs against the corresponding and expected public key. These properties are used in practice for a variety of use cases, ranging from identity or data authenticity to non-repudiation. Unsurprisingly, signature schemes are …
