Smart Certificate using Blockchain

NECTAR: Non-Interactive Smart Contract Protocol using Blockchain Technology

Blockchain-driven technologies are considered disruptive because of the availability of dis-intermediated, censorship-resistant and tamper-proof digital platforms of distributed trust. Among these technologies, smart contract platforms have the potential to take over functions usually done by intermediaries like banks, escrow or legal services. In this paper, we introduce a novel protocol aimin...

Improving data transparency in clinical trials using blockchain smart contracts

The scientific credibility of findings from clinical trials can be undermined by a range of problems including missing data, endpoint switching, data dredging, and selective publication. Together, these issues have contributed to systematically distorted perceptions regarding the benefits and risks of treatments. While these issues have been well documented and widely discussed within the profe...

Risks and Opportunities for Systems Using Blockchain and Smart Contracts

Using Blockchain and smart contracts for secure data provenance management

Blockchain technology has evolved from being an immutable ledger of transactions for cryptocurrencies to a programmable interactive environment for building distributed reliable applications. Although, blockchain technology has been used to address various challenges, to our knowledge none of the previous work focused on using blockchain to develop a secure and immutable scientific data provena...

Limitations Regarding Certificate Handling on Smart Cards

A public-key infrastructure (PKI) typically requires use of tamper-proof devices that can perform crypto computations and store highly sensitive data like private keys. Smart cards are the low cost devices that satisfy these requirements and, as a result, they can boost the wide deployment of a PKI. Yet certain limitations exist regarding the handling of certificates, one of the supporting mech...
