We derive a new entropic quantum uncertainty relation involving min-entropy. The relation is tight and can be applied in various quantum-cryptographic settings. Protocols for quant...
Round complexity is a central measure of efficiency, and characterizing the round complexity of various cryptographic tasks is of both theoretical and practical importance. We show...
A secure multicast framework should only allow authorized members of a group to decrypt received messages; usually, one ‘‘group key’’ is shared by all approved members. Ho...
In wireless roaming a mobile device obtains a service from some foreign network while being registered for the similar service at its own home network. However, recent proposals tr...
In a society increasingly concerned with the steady assault on electronic privacy, the need for privacy-preserving techniques is both natural and justified. This need extends to t...
