Verifiably Encrypted Signature Scheme with Threshold Adjudication
M. Choudary Gorantla and Ashutosh Saxena
Abstract
Verifiably encrypted signature is useful in handling the fair exchange problem especially, online contract signing. In this paper, we propose a verifiably encrypted signature scheme using bilinear pairings. Our scheme facilitates the adjudication to be done in a threshold manner to achieve robustness. We show that the distribution of adjudication capability is robust and unforgeable. Our scheme is secure against extraction and existential forgery in the random oracle model.
