Escrow Protocols for Cryptocurrencies: How to Buy Physical Goods Using Bitcoin [chapter]

Steven Goldfeder, Joseph Bonneau, Rosario Gennaro, Arvind Narayanan
2017 Lecture Notes in Computer Science  
Our schemes are compatible with Bitcoin and similar blockchain-based cryptocurrencies.  ...  However, we show that naive escrow protocols introduce both privacy and security issues. We formalize the escrow problem and present a suite of schemes with improved security and privacy properties.  ...  This was either because it relied on an older form of electronic cash in which the signed statement served as a bearer token and anyone bearing it could cash in the money, or it was due to the fact that  ...

Two Improved Partially Blind Signature Schemes from Bilinear Pairings [chapter]

Sherman S. M. Chow, Lucas C. K. Hui, S. M. Yiu, K. P. Chow
2005 Lecture Notes in Computer Science  
In this paper, we propose a threshold partially blind signature scheme from bilinear pairings and an ID-based partially blind signature scheme, which are provably secure in the random oracle model.  ...  To the best of authors' knowledge, we give the first discussion on these two notions.  ...  Fangguo Zhang for pointing out the mistake of the preliminary version of this paper (by showing a changing agreed information attack on the scheme) and all the anonymous reviewers for their helpful comments  ...

Strongly Unforgeable and Efficient Proxy Signature Scheme with Fast Revocation Secure in the Standard Model

Liaojun Pang, Huiyang Zhao, Xia Zhou, Huixian Li
2016 International Journal of Distributed Sensor Networks  
Analyses show that the proposed scheme satisfies all of the security requirements of proxy signature and has shorter public parameters than the existing ones.  ...  Motivated by these concerns, a new proxy signature scheme with fast revocation is proposed, and it can be proved that the proposed scheme can achieve strong unforgeability in the standard model.  ...  [24] constructed the provably secure ID-based proxy signature schemes based on the lattice International Journal of Distributed Sensor Networks 3 problems, respectively and independently, but these  ...

Witness Hiding Proofs and Applications

Chen Lidong
1994 DAIMI Report Series  
Two election schemes are proposed and discussed. Especially the voting scheme is parallelized with electronic cash system so that some new tool can be introduced.  ...  The parallel divertibility is not only of theoretical significance but also a crucial point for the security of some applications, for example, electronic cash, digital signatures, etc.  ...  In the second election scheme, a "voting coin" is constructed to certify the voters, which is based on electronic cash.  ...

Strong Federations: An Interoperable Blockchain Solution to Centralized Third-Party Risks [article]

Johnny Dilley, Andrew Poelstra, Jonathan Wilkins, Marta Piekarska, Ben Gorlick, Mark Friedenbach
2017 arXiv   pre-print
Bitcoin, the first peer-to-peer electronic cash system, opened the door to permissionless, private, and trustless transactions.  ...  In Liquid, Bitcoin's proof-ofwork is replaced with a k-of-n multisignature scheme.  ...  A federated model offers another solution, with a fixed signer set, in which the DMMS is replaced with a traditional multisignature scheme.  ...

In 2007, Camenisch, Neven and Shelat proposed an adap-tive oblivious transfer (OT) scheme in which a sender has n messages, of which a receiver can adaptively choose to receive k one-after-the-other.  ...  In this paper, we show that the scheme has a drawback that the sender can serve a single receiver only once. The drawback results from the deterministic encryption used.  ...  Then a provably secure and efficient scheme based on quadratic residue is proposed.  ...
