Simulation-based Receiver Selective Opening CCA Secure PKE from Standard Computational Assumptions
public key encryption receiver selective opening security chosen ciphertext security
2018/11/12
In the situation where there are one sender and multiple receivers, a receiver selective opening (RSO) attack for a public key encryption (PKE) scheme considers adversaries that can corrupt some of th...
Simulation-Based Selective Opening Security for Receivers under Chosen-Ciphertext Attacks
simulation-based security selective opening security for receivers chosen-ciphertext attacks
2018/8/21
Security against selective opening attack (SOA) for receivers requires that in a multi-user setting, even if an adversary has access to all ciphertexts, and adaptively corrupts some fraction of the us...
Key Dependent Message Security and Receiver Selective Opening Security for Identity-Based Encryption
Identity-based encryption Key dependent message security Receiver selective opening security
2017/10/10
We construct two identity-based encryption (IBE) schemes. The first one is IBE satisfying key dependent message (KDM) security for user secret keys. The second one is IBE satisfying simulation-based r...
All-But-Many Lossy Trapdoor Functions and Selective Opening Chosen-Ciphertext Security from LWE
LWE lossy trapdoor functions chosen-ciphertext security
2017/9/14
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 senders' random co...
Selective Opening Security from Simulatable Data Encapsulation
selective opening hybrid encryption mode of operation
2016/12/10
The confidentiality notion of security against selective opening attacks considers adversaries
that obtain challenge ciphertexts and are allowed to adaptively open them, thereby revealing
the encryp...
Selective-Opening Security in the Presence of Randomness Failures
selective-opening security deterministic encryption nonce-based PKE
2016/12/9
We initiate the study of public-key encryption (PKE) secure against selective-opening attacks (SOA) in
the presence of randomness failures, i.e., when the sender may (inadvertently) use low-quality r...

2016/12/7
We present a general construction of RSO security against chosen ciphertext attacks (RSO-CCA) by combining any RSO secure scheme against chosen plaintext attacks (RSO-CPA) with any regular CCA secure ...

We show that two well-known and widely employed public-key encryption schemes – RSA Optimal

(DHIES), instanti...
Public-Key Encryption with Simulation-Based Selective-Opening Security and Compact Ciphertexts
Public-key encryption selective-opening security lossy encryption
2016/2/24
In a selective-opening (SO) attack on an encryption scheme, an adversary A gets a number of ciphertexts (with possibly related plain- texts), and can then adaptively select a subset of those ciphertex...
Simulation-based Selective Opening CCA Security for PKE from Key Encapsulation Mechanisms
public-key cryptography selective opening
2016/1/5
We study simulation-based, selective opening security against chosen-ciphertext attacks (SIM-SO-CCA security) for public key encryption (PKE). In a selective opening, chosen-ciphertext attack (SO-CCA)...

Security against selective opening attack (SOA) requires that in a multi-user setting, even
if an adversary has access to all ciphertexts from users, and adaptively corrupts some fraction of the
use...
Non-malleability under Selective Opening Attacks: Implication and Separation
public-key encryption, non-malleability, selective opening attack
2015/12/31
We formalize the security notions of non-malleability under selective opening attacks
(NM-SO security) in two approaches: the indistinguishability-based approach and the simulationbased
approach. We...
Standard Security Does Not Imply Indistinguishability Under Selective Opening
selective opening attack encryption scheme
2015/12/24
In a selective opening attack (SOA) on an encryption scheme, the adversary is given a collection of
ciphertexts and selectively chooses to see some subset of them \opened", meaning that the messages ...

2015/12/23
About three decades ago it was realized that implementing private channels between parties
which can be adaptively corrupted requires an encryption scheme that is secure against selective
opening at...

In a selective opening (SO) attack an adversary breaks into a subset of honestly created ciphertexts
and tries to learn information on the plaintexts of some untouched (but potentially related) ciphe...
