Improvement of an Eliptic Curve Based Threshold Proxy Signature Scheme

Improvement of an Eliptic Curve Based Threshold Proxy Signature Scheme

In 2006, Pomykala et al. proposed an elliptic curve based threshold proxy signature scheme as well as a proxy-protected version. They claimed their scheme had the properties of secrecy, unforgeability, non-repudiation and signer’s identification. In this study, we showed inter conspiracy attack on t...

They claimed their scheme had the properties of secrecy, unforgeability, non-repudiation and signer’s identification. In this study, we showed inter conspiracy attack on the basic scheme and gave another attack on the proxy-protected version. We pointed out that even if the central authority is engaged, the basic model is not a proxy-protected one. We also proposed an improved scheme that can resist the known attacks to achieve higher security, and gave the security analysis of the improved scheme in detail.http://dx.doi.org/10.1051/matecconf/20164402017
