A Black-Box Construction of Non-Malleable Encryption from Semantically Secure Encryption
Non-Malleable Encryption Semantically Secure Encryption
2016/7/22
We show how to transform any semantically secure encryption scheme into a non-malleable one, with a black-box construction that achieves a quasi-linear blow-up in the size of the ciphertext. This impr...
Semantically Secure Anonymity: Foundations of Re-encryption
probabilistic re-encryption key anonymity anonymous communication
2016/4/6
The notion of universal re-encryption is an established primitive used in the design of many anonymity protocols. It allows anyone to randomize a ciphertext without changing its size, without decrypti...
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...
Semantically Secure Order-Revealing Encryption: Multi-Input Functional Encryption Without Obfuscation
functional encryption multilinear maps
2016/1/6
Deciding “greater-than” relations among data items just given their encryptions is at the heart of
search algorithms on encrypted data, most notably, non-interactive binary search on encrypted data.

Obfuscation from Semantically-Secure Multi-linear Encodings
obfuscation semantically secure
2014/3/5
We define a notion of semantic security of multi-linear (a.k.a. graded) encoding schemes: roughly speaking, we require that if an algebraic attacker (obeying the multi-linear restrictions) cannot tell...
A semantically secure elliptic curve RSA scheme with small expansion factor
public-key cryptography semantic security expansion factor
2009/4/14
We propose an elliptic curve scheme over the ring Zn2 , which is efficient
and semantically secure in the standard model, and it has expansion
factor 2 (previous schemes with similar features presen...
An efficient semantically secure elliptic curve cryptosystem based on KMOV
public-key cryptography semantic security elliptic curves
2009/4/13
We propose an elliptic curve scheme over the ring Zn2 , which is efficient
and semantically secure in the standard model. There appears to be no previous
elliptic curve cryptosystem based on factori...
