- With the emergence of Searchable Encryption algorithms enabling the retrieval of encrypted outsourced contents without decrypting them, inference attacks in multi-user contexts have increased, making practical use of Searchable Encryption difficult. This paper proposes to resolve the problematic trade-off between utility and security, relying on lightweight cryptographic primitives while ensuring query expressiveness and secure users’ revocation. The proposed theoretical solution is integrated into a privacy-preserving publish/subscribe application (Content Data Network), in the “Secure data-centric architecture and its applications” research project funded by the Australian funding body CSIRO - Commonwealth Scientific and Industrial Research Organisation (GNo G1900931).
