A multitude of systems and methods are provided. An encryption method and system utilizing vector label input threshold encryption is included, enabling decentralized confidentiality and decentralized, fine-grained, and attributed-based access control, enabling clients to define by whom, when, and how their data is accessed. Additionally, the disclosed systems and methods can include publish/subscribe mechanisms while achieving confidentiality-preserving and decoupled publish/subscribe messaging and strong total order for publications even with crytographic access control enforced.
