Two-Party Computing with Encrypted Data
We consider a new model for online secure computation on encrypted inputs in the presence of malicious adversaries. The inputs are independent of the circuit computed in the sense ...

Hedged Public-Key Encryption: How to Protect against Bad Randomness
Abstract. Public-key encryption schemes rely for their IND-CPA security on per-message fresh randomness. In practice, randomness may be of poor quality for a variety of reasons, le...

Conditional proxy re-encryption secure against chosen-ciphertext attack
In a proxy re-encryption (PRE) scheme [4], a proxy, authorized by Alice, transforms messages encrypted under Alice's public key into encryptions under Bob's public key w...

Collusion Resistant Broadcast Encryption with Short Ciphertexts and Private Keys
We describe two new public key broadcast encryption systems for stateless receivers. Both systems are fully secure against any number of colluders. In our first construction both...
