Chosen-Ciphertext Secure Identity-Based Encryption in the Standard Model With Short Ciphertexts
January 1, 2011, 12:00am PST
The authors describe a practical identity-based encryption scheme that is secure in the standard model against chosen-ciphertext (IND-CCA2) attacks. Security is based on an assumption comparable...

Security and Composability of Randomness Expansion from Bell Inequalities
March 2, 2012, 12:00am PST
The nonlocal behavior of quantum mechanics can be used to generate guaranteed fresh randomness from an untrusted device that consists of two nonsignalling components; since the generation process...
