Abstract
In this paper, a certificateless aggregate signature scheme for blockchain- based electronic medical record (EMR) is proposed, which has the characteristics of decentralization, security, credibility and tamper-proof. Performance analysis shows that the proposed scheme has constant communication cost and low computational cost. This scheme can be utilized to tackle difficult problems in regard to identity authentication in EMR. It can also preserve the integrity of EMR data.
