A formal treatment to the privacy of concealed data aggregation (CDA) is given. While there exist a handful of constructions, rigorous security models and analyses for CDA are stil...
Compact and high-speed hardware architectures and logic optimization methods for the AES algorithm Rijndael are described. Encryption and decryption data paths are combined and all...
—We propose a new DRM architecture that utilizes a two-step enforcement process to enable strong security even in the case of a compromised DRM viewer. This is achieved by using ...
It is a well known fact that encryption schemes cannot hide a plaintext length when it is unbounded. We thus admit that an approximation of it may leak and we focus on hiding its p...
The Galois/Counter Mode (GCM) of operation has been standardized by NIST to provide single-pass authenticated encryption. The GHASH authentication component of GCM belongs to a cla...
