Simple and Efficient KDM-CCA Secure Public Key Encryption
key dependent message security chosen ciphertext security
2019/9/16
We propose two efficient public key encryption (PKE) schemes satisfying key dependent message security against chosen ciphertext attacks (KDM-CCA security). The first one is KDM-CCA secure with respec...
Structure-Preserving and Re-randomizable RCCA-secure Public Key Encryption and its Applications
public-key cryptography Rand-RCCA PKE
2019/8/22
Re-randomizable RCCA-secure public key encryption (Rand-RCCA PKE) schemes reconcile the property of re-randomizability of the ciphertexts with the need of security against chosen-ciphertexts attacks.

We propose a framework for achieving a public-key encryption (PKE) scheme that satisfies key dependent message security against chosen ciphertext attacks (KDM-CCA security) based on projective hash fu...
Tightly SIM-SO-CCA Secure Public Key Encryption from Standard Assumptions
selective opening public-key cryptography SIM-SO-CCA
2018/1/11
Selective opening security (SO security) is desirable for public key encryption (PKE) in a multi-user setting. {In a selective opening attack, an adversary receives a number of ciphertexts for possibl...
KDM-Secure Public-Key Encryption from Constant-Noise LPN
learning parity with noise key-dependent message security public-key encryption
2017/4/12
The Learning Parity with Noise (LPN) problem has found many applications in cryptography due to its conjectured post-quantum hardness and simple algebraic structure. Over the years, constructions of d...

2016/12/10
KDM[F][F]-CCA secure public-key encryption (PKE) protects the security of message f(sk)f(sk), with f∈Ff∈F, that is computed directly from the secret key, even if the adversary has access to a decrypti...

Public Key Encryption randomized algorithms
2016/6/2
We describe a general technique to protect randomized algorithms against kleptographic attacks. We then apply the technique to construct the first IND-CPA secure public-key encryp- tion scheme in the ...
Generic Transformation of a CCA2-Secure Public-Key Encryption Scheme to an eCK-Secure Key Exchange Protocol in the Standard Model
Department of Computer Engineering,University of Peradeniya
2016/1/26
LaMacchia, Lauter and Mityagin presented a strong security model for authenticated key agreement, namely the eCK model. They also constructed a protocol, namely the NAXOS protocol, that enjoys a simpl...
Bounded-Collusion Identity-Based Encryption from Semantically-Secure Public-Key Encryption: Generic Constructions with Short Ciphertexts
Identity-based encryption Bounded-CCA security
2016/1/26
Identity-based encryption (IBE) is a special case of public-key encryption where
user identities replace public keys. Every user is given a corresponding secret key for decryption,
and encryptions f...

Brief History Provably-Secure Public-Key Encryption
2009/6/12
Public-key encryption schemes are a useful and interesting
field of cryptographic study. The ultimate goal for the cryptographer in
the field of public-key encryption would be the production of a ve...
