Threshold Schemes with Disenrollment
Blakley, Blakley, Chan and Massey conjectured a lower bound on the entropy of broadcast messages in threshold schemes with disenrollment. In an effort to examine the conjecture, w...

Practical Threshold Signatures Without Random Oracles
We propose a secure threshold signature scheme without trusted dealer. Our construction is based on the recently proposed signature scheme of Waters in EUROCRYPT’05. The new thre...

Construction of Threshold Public-Key Encryptions through Tag-Based Encryptions
In this paper, we propose a notion of threshold tag-based encryption schemes that simplifies the notion of threshold identity-based encryption schemes, and we show a conversion fro...

On the Security of Some Nonrepudiable Threshold Proxy Signature Schemes
A (t, n) threshold proxy signature scheme enables an original signer to delegate the signature authority to a proxy group of n member such that t or more than t proxy signers can ...

On the Security of Two Threshold Signature Schemes with Traceable Signers
A (t, n) threshold signature scheme allows t or more group members to generate signatures on behalf of a group with n members, while any t−1 or less members cannot do the same th...
