Generic constructions of secure-channel free searchable encryption with adaptive security
For searching keywords against encrypted data, the public key encryption scheme with keyword search (PEKS), and its an extension called secure-channel free PEKS (SCF-PEKS) have been proposed. In SCF-PEKS, a receiver makes a trapdoor for a keyword, and uploads it on a server. A sender computes an encrypted keyword, and sends it to the server. The server executes the searching procedure (called t...
متن کاملGeneric Adaptively Secure Searchable Phrase Encryption
In recent years searchable symmetric encryption has seen a rapid increase in query expressiveness including keyword, phrase, Boolean, and fuzzy queries. With this expressiveness came increasingly complex constructions. Having these facts in mind, we present an efficient and generic searchable symmetric encryption construction for phrase queries. Our construction is straightforward to implement,...
متن کاملUC-Secure Searchable Symmetric Encryption
For searchable symmetric encryption schemes (or symmetrickey encryption with keyword search), the security against passive adversaries (i.e. privacy) has been mainly considered so far. In this paper, we first define its security against active adversaries (i.e. reliability as well as privacy). We next formulate its UC-security. We then prove that the UCsecurity against non-adaptive adversaries ...
متن کاملAdaptive Secure-Channel Free Public-Key Encryption with Keyword Search Implies Timed Release Encryption
As well-known results, timed-release encryption (TRE) and public key encryption scheme with keyword search (PEKS) are very close to identity-based encryption (IBE), respectively. It seems natural that there is a close relationship between TRE and PEKS. However, no explicit bridge has been shown between TRE and PEKS so far. In this paper, we show that TRE can be generically constructed by PEKS w...
متن کاملGeneric Constructions for Chosen-Ciphertext Secure Attribute Based Encryption
In this paper we propose generic conversions for transforming a chosen-plaintext (CPA) secure attribute-based encryption (ABE) to a chosen-ciphertext (CCA) secure ABE. The only known generic conversion, to the best of our knowledge, was presented by Goyal et al. in ACM-CCS 2006, which itself subsumes the well-known IBE-to-PKE conversion by Canetti, Halevi, and Katz proposed in Eurocrypt 2004. T...
