Insight of the protection for data security under selective opening attacks
Data security and privacy protection issues are the primary restraints for adoption of cloud
computing. Selective opening security (SOA security) focuses on such a scenario of cloud …

Lossy encryption: Constructions from general assumptions and efficient selective opening chosen ciphertext security
Lossy encryption was originally studied as a means of achieving efficient and composable
oblivious transfer. Bellare, Hofheinz and Yilek showed that lossy encryption is also selective …

Identity-based encryption secure against selective opening attack
We present the first IBE schemes that are proven secure against selective opening attack
(SOA). This means that if an adversary, given a vector of ciphertexts, adaptively corrupts …

All-but-many lossy trapdoor functions
D Hofheinz - Annual International Conference on the Theory and …, 2012 - Springer
We put forward a generalization of lossy trapdoor functions (LTFs). Namely, all-but-many
lossy trapdoor functions (ABM-LTFs) are LTFs that are parametrized with tags. Each tag can …

Standard security does not imply security against selective-opening
We show that no commitment scheme that is hiding and binding according to the standard
definition is semantically-secure under selective opening attack (SOA), resolving a long …

All-but-many lossy trapdoor functions and selective opening chosen-ciphertext security from LWE
Selective opening (SO) security refers to adversaries that receive a number of ciphertexts
and, after having corrupted a subset of the senders (thus obtaining the plaintexts and the …

Standard security does not imply indistinguishability under selective opening
In a selective opening attack (SOA) on an encryption scheme, the adversary is given a
collection of ciphertexts and she selectively chooses to see some subset of them “opened” …

On definitions of selective opening security
F Böhl, D Hofheinz, D Kraschewski - … on Practice and Theory in Public Key …, 2012 - Springer
Assume that an adversary observes many ciphertexts, and may then ask for openings, ie the
plaintext and the randomness used for encryption, of some of them. Do the unopened …

Semantically-secure functional encryption: Possibility results, impossibility results and the quest for a general definition
This paper explains that SS1-secure functional encryption (FE) as defined by Boneh, Sahai
and Waters implicitly incorporates security under key-revealing selective opening attacks …
