Due to the popularity of blockchain, there have been many proposed applications of
blockchain in the healthcare sector, such as electronic health record (EHR) systems …

Blockchain is a disruptive technology for shaping the next era of a healthcare system striving
for efficient and effective patient care. This is thanks to its peer-to-peer, secure, and …

Electronic medical record (EMR) is a crucial form of healthcare data, currently drawing a lot
of attention. Sharing health data is considered to be a critical approach to improve the …

We describe a working implementation of a variant of Gentry's fully homomorphic encryption
scheme (STOC 2009), similar to the variant used in an earlier implementation effort by Smart …

We introduce and formally define polynomial commitment schemes, and provide two
efficient constructions. A polynomial commitment scheme allows a committer to commit to a …

Thanks to the widespread deployment of TLS, users can access private data over channels
with end-to-end confidentiality and integrity. What they cannot do, however, is prove to third …

We construct the first homomorphic signature scheme that is capable of evaluating
multivariate polynomials on signed data. Given the public key and a signed data set, there is …

We propose a linearly homomorphic signature scheme that authenticates vector subspaces
of a given ambient space. Our system has several novel properties not found in previous …

We introduce the notion of sanitizable signatures that offer many attractive security features
for certain current and emerging applications. A sanitizable signature allows authorized …

A functional commitment scheme enables a user to concisely commit to a function from a
specified family, then later concisely and verifiably reveal values of the function at desired …
