Lattice-Based Public Key Cryptosystem Provably Secure against Adaptive Chosen Ciphertext Attack
Lattice CCA-security Matrix encryption Pseudohomomorphism
2010/3/16
We propose a simple and ecient construction of CCA- secure
public-key encryption scheme based on lattice. Our construction
needs an encryption scheme, which we call \matrix encryption", as building...
Design and Analysis of Practical Public-Key Encryption Schemes Secure against Adaptive Chosen Ciphertext Attack
Practical Public-Key Encryption Schemes Secure Adaptive Chosen Ciphertext Attack
2009/4/16
A new public key encryption scheme, along with several variants, is proposed and analyzed.
The scheme and its variants are quite practical, and are proved secure against adaptive chosen
ciphertext a...
Public Key Trace and Revoke Scheme Secure against Adaptive Chosen Ciphertext Attack
Public Key Trace Revoke Scheme Secure Adaptive Chosen Ciphertext Attack
2009/4/9
A (public key) Trace and Revoke Scheme combines the functionality of broadcast encryption
with the capability of traitor tracing. Specifically, (1) a trusted center publishes a single public key and ...
