AB  - Along with the increase of wearable medical device, the privacy leakage 
problem in the process of transmission between these edge medical devices. The
blockchain-enabled Internet of Medical Things (BIoMT) has been developed to 
reform traditional centralized medical system in recent years. This paper first 
introduces a data anonymous authentication model to protect user privacy and 
medical data in BIoMT. Then, a proxy group signature (PGS) scheme has been 
proposed based on lattice assumption. This scheme can well satisfy the anonymous 
authentication demand for the proposed model, and provide anti-quantum attack 
security for BIoMT in the future general quantum computer age. Moreover, the 
security analysis shows this PGS scheme is secure against the dynamical-almostfull anonymous and traceability. The efficiency comparison shows the proposed 
model and PGS scheme is more efficient and practical.
