Information Flow in Secret Sharing Protocols
The entangled graph states [9] have emerged as an elegant and powerful quantum resource, indeed almost all multiparty protocols can be written in terms of graph states including measurement based quantum computation (MBQC), error correction and secret sharing amongst others. In addition they are at the forefront in terms of implementations. As such they represent an excellent opportunity to mov...
متن کاملSecret Sharing and Shared Information
Secret sharing is a cryptographic discipline in which the goal is to distribute information about a secret over a set of participants in such a way that only specific authorized combinations of participants together can reconstruct the secret. Thus, secret sharing schemes are systems of variables in which it is very clearly specified which subsets have information about the secret. As such, the...
متن کاملSecret Sharing Schemes with Applications in Security Protocols
Preface A secret sharing scheme starts with a secret and then derives from it certain shares (or shadows) which are distributed to users. The secret may be recovered only by certain predetermined groups which belong to the access structure. Secret sharing schemes have been independently introduced by Blakley [12] and Shamir [134] as a solution for safeguarding cryptographic keys. Secret sharing...
متن کاملInformation-theoretically Secure Strong Verifiable Secret Sharing
In a (t,n) secret sharing scheme, a mutually trusted dealer divides a secret into n shares in such a way that any t or more than t shares can reconstruct the secret, but fewer than t shares cannot reconstruct the secret. When there is no mutually trusted dealer, a (n,t,n) secret sharing scheme can be used to set up a (t,n) secret sharing because each shareholder also acts as a dealer to decide ...
متن کاملEfficient Sealed-Bid Auction Protocols Using Verifiable Secret Sharing
This article proposes efficient solutions for the construction of sealed-bid second-price and combinatorial auction protocols in an active adversary setting. The main reason for constructing secure auction protocols is that the losing bids can be used in the future auctions as well as negotiations if they are not kept private. Our motivation is to apply verifiable secret sharing in order to con...
