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...
As such, public-key encryption with keyword search (a.k.a PEKS or searchable encryption) does not allow the recipient to decrypt keywords i.e. encryption is not invertible. This pa...
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...
Currently, the requirements on MPEG encryption algorithms include: fast speed, format compliance, a wide range of security levels, easy implementation, etc. However, promising can...
There are several candidate semantically secure encryption schemes, yet in many applications non-malleability of encryptions is crucial. We show how to transform any semantically s...
