Authenticating mobile computing users can require a significant amount of processing and communications resources— particularly when protocols based on public key encryption are...
We present two transforms to acquire chosen ciphertext security from tag based techniques. The first one requires the separability of underlying primitives. By separability, info...
Imagine many small devices send data to a single receiver, encrypted using the receiver’s public key. Assume an adversary that has the power to adaptively corrupt a subset of the...
