Injection-Secure Structured and Searchable Symmetric Encryption

ePrint Report: Injection-Secure Structured and Searchable Symmetric Encryption

Ghous Amjad, Seny Kamara, Tarik Moataz

Recent work on dynamic structured and searchable symmetric encryption has focused on achieving the notion of forward-privacy. This is mainly motivated by the claim that forward-privacy protects against adaptive file injection attacks (Zhang, Katz, Papamanthou, Usenix Security, 2016). In this work, we revisit the notion of forward-privacy in several respects. First, we observe that forward-privacy does not necessarily guarantee security against adaptive file injection attacks if …
