Public-key Cryptosystem Post-Quantum Cryptosystem Indeterminate Equation
2017/12/25
In this paper, we propose a post-quantum public-key encryption scheme whose security depends on a problem arising from a multivariate non-linear indeterminate equation. The security of lattice cryptos...

Lattice based encryption schemes and linear code based encryption schemes have received extensive
attention in recent years since they have been considered as post-quantum candidate encryption scheme...
Efficient CCA-secure Threshold Public-Key Encryption Scheme
Chosen-ciphertext security Hashed Diffie-Hellman assumption
2014/3/6
In threshold public-key encryption, the decryption key is divided into n shares, each one of which is given to a different decryption user in order to avoid single points of failure. In this study, we...

We show that a recently proposed construction by Rosen and Segev can be
used for obtaining the first public key encryption scheme based on the McEliece
assumptions which is secure against adaptive c...

public key encryption scheme plaintext ciphertext attacks
2009/6/9
Recently, at Crypto 2008, Boneh, Halevi, Hamburg, and Ostrovsky (BHHO) solved the longstanding
open problem of "circular encryption," by presenting a public key encryption scheme
and proving that it...

2009/4/10
At Eurocrypt 2003, Augot and Finiasz proposed a new public-key encryp-
tion scheme based on the polynomial reconstruction problem [1]. The scheme was subse-
quently broken in [5], who showed that gi...

Bilinear Diffe-Hellman Encryption Binary-tree encryption
2009/4/9
Cryptographic computations are often carried out on insecure devices for which the threat
of key exposure represents a serious and realistic concern. In an e ort to mitigate the damage
caused by exp...
