Contract Signing Using PGP
Is it possible to achieve non-repudiation during electronic contractsigning? How can this be achieved in an e-mail based environment? These are the questions we will try to answer. The process of getting these answers will involve a short introduction to some of the available contract-signing standards and an analysis of how well the given standard would work in a e-mail environment. Additional...
متن کاملQuantum contract signing
We present a probabilistic quantum contract signing protocol between two clients that requires no communication with the third trusted party during the commitment (i.e. signature exchange) phase. We discuss its fairness and show that it is possible to design such a protocol for which the probability of a dishonest client to cheat becomes negligible, and scales as N−1/2, where N is the size of t...
متن کاملPoster: Bitcoin Meets Collective Signing
While showing great promise, Bitcoin requires users to wait tens of minutes for transactions to commit – even then offering only probabilistic guarantees. This work introduces ByzCoin, a novel Byzantine consensus protocol that leverages scalable collective signing to commit Bitcoin transactions irreversibly within seconds. ByzCoin achieves Byzantine consensus while preserving Bitcoin’s open mem...
متن کاملAbuse-Free Optimistic Contract Signing
We introduce the notion of abuse-free distributed contract signing, that is, distributed contract signing in which no party ever can prove to a third party that he is capable of choosing whether to validate or invalidate the contract. Assume Alice and Bob are signing a contract. If the contract protocol they use is not abuse-free, then it is possible for one party, say Alice, at some point to c...
متن کاملSigning on a Postcard
We investigate the problem of signing short messages using a scheme that minimizes the total length of the original message and the appended signature. This line of research was motivated by several postal services interested by stamping machines capable of producing digital signatures. Although several message recovery schemes exist, their security is questionable. This paper proposes variants...
