Tight Leakage-Resilient CCA-Security from Quasi-Adaptive Hash Proof System
public-key encryption leakage-resilience CCA security
2019/5/21
We propose the concept of quasi-adaptive hash proof system (QAHPS), where the projection key is allowed to depend on the specific language for which hash values are computed. We formalize leakage-resi...
Super-Strong RKA Secure MAC, PKE and SE from Tag-based Hash Proof System
related-key attack hash proof system message authentication code
2016/12/7
In this paper, we define new RKA security notions for several cryptographic primitives including message authentication code (MAC), public-key encryption (PKE) and symmetric encryption (SE). This new ...
Leakage-Resilient Chosen-Ciphertext Secure Public-Key Encryption from Hash Proof System and One-Time Lossy Filter
Public-key encryption leakage-resilience
2014/3/7
We present a new generic construction of a public-key encryption (PKE) scheme secure against leakage-resilient chosen-ciphertext attacks (LR-CCA), from any Hash Proof System (HPS) and any one-time los...
Generalized (Identity-Based) Hash Proof System and Its Applications
hash proof system leakage-resilience anonymity public-key encryption with keyword search
2013/2/21
In this work, we generalize the paradigm of hash proof system (HPS) proposed by Cramer and Shoup [CS02]. In the central of our generalization, we lift subset membership problem to distribution disting...
