Public Key Compression and Modulus Switching for Fully Homomorphic Encryption over the Integers
We describe a compression technique that reduces the public key size of van Dijk, Gentry, Halevi and Vaikuntanathan’s (DGHV) fully homomorphic scheme over the integers from ˜O(...

Construction of Threshold Public-Key Encryptions through Tag-Based Encryptions
In this paper, we propose a notion of threshold tag-based encryption schemes that simplifies the notion of threshold identity-based encryption schemes, and we show a conversion fro...

Public Key Encryption and Encryption Emulation Attacks
The main purpose of this paper is to show that public key encryption can be secure against the "encryption emulation" attack (on the sender's encryption) by computat...

Universally Anonymizable Public-Key Encryption
Abstract. We first propose the notion of universally anonymizable publickey encryption. Suppose that we have the encrypted data made with the same security parameter, and that the...

Adaptively-Secure, Non-interactive Public-Key Encryption
Adaptively-secure encryption schemes ensure secrecy even in the presence of an adversary who can corrupt parties in an adaptive manner based on public keys, ciphertexts, and secret...
