Workshop on Decentralized Secure Collaboration
Cryptography for collaboration without a single trusted controller.
Monday, 7 December 2026 · Hong Kong
Workshop overview
Modern collaboration systems increasingly operate without a single trusted controller. Users, servers, committees, wallets, ledgers, auditors, and verifiers may participate in a common system, while no one party should hold all keys, observe all data, decide all access, or be trusted to report the outcome.
The workshop covers threshold and distributed cryptography, privacy-preserving authentication, zero-knowledge proofs, verifiable computation, post-quantum migration, and deployed cryptographic systems.
Topics
Three system-facing lenses guide the workshop program and discussion.
Control and authorization
How can a shared system determine who may act, rotate or recover keys, authorize state changes, or represent a group? Relevant techniques include threshold signatures, MPC signing, distributed key management, wallets, custody, and decentralized governance.
Private participation and authentication
How can a party prove eligibility, status, reputation, or contribution without unnecessary disclosure? We welcome work on anonymous authentication, anonymous credentials, private tokens, revocation, abuse resistance, and decentralized identity.
Verification and accountability
How can others audit outcomes, check compliance, or verify private computation without seeing private inputs? Relevant techniques include zero-knowledge proofs, SNARKs, proof aggregation, verifiable computation, auditability without disclosure, and verification of private state.
These lenses are not independent tracks: they often coexist within one collaborative system. WDSC particularly welcomes contributions connecting at least two functions, or addressing cross-cutting challenges such as trust-model composition, key lifecycle, recovery and rotation, failure handling, interoperability, APIs, benchmarking, post-quantum migration, or deployment. Work focused on one primitive is also welcome when its role in decentralized secure collaboration is explicit.
