On the plausibility of simulation based security in Multi Key Searchable Encryption with short share keys
Manuela Horduna · Procedia Computer Science · 2024
In the multi-key searchable encryption scenario, individuals save their encrypted fles on a distant computer system, having the ability to retrieve them. An individual should have the ability to conduct keyword searches and also to have access to all documents, even those shared by others. The information within the documents and the search requests must be kept confidential from the server. The aim of this paper is to propose a stronger definition of simulation based security for a multi key searchable encryption with short share keys scheme. Then, we work on creating a link between indistinguishability based security and simulation based security through designing a simulator that meets our specified standards.
