Cryptographically-masked flows
Abstract. Cryptographic operations are essential for many security-critical systems. Reasoning about information flow in such systems is challenging because typical (noninterferenc...

A Secure Key Registration System based on Proactive Secret-Sharing Scheme
We designed a secure key registration system based on the proactive secret-sharing scheme. A user can register important data such as a session key to a distributed system in a (t...

CCA2-Secure Threshold Broadcast Encryption with Shorter Ciphertexts
In a threshold broadcast encryption scheme, a sender chooses (ad-hoc) a set of n receivers and a threshold t, and then encrypts a message by using the public keys of all the recei...

Security analysis of cryptographically controlled access to XML documents
Some promising recent schemes for XML access control employ encryption for implementing security policies on published data, avoiding data duplication. In this paper we study one ...

The Bare Bounded-Storage Model: The Tight Bound on the Storage Requirement for Key Agreement
Abstract--In the bounded-storage model (BSM) for information-theoretic secure encryption and key agreement, one makes use of a random string R whose length t is greater than the as...
