Data sharing is an important functionality in cloud storage. In this paper, we show how to
securely, efficiently, and flexibly share data with others in cloud storage. We describe new …

In this paper, we explore a new direction towards solving the identity authentication problem
in RFID systems. We break the RFID authentication process into two main problems …

Message authentication codes (MACs) based on universal hash-function families are
becoming increasingly popular due to their fast implementation. In this paper, we investigate …

The recent advent of cloud computing and the IoT has made it imperative to have efficient
and secure cryptographic schemes for online data sharing. Data owners would ideally want …

Universal hashing, discovered by Carter and Wegman in 1979, has many important
applications in computer science. MMH∗, which was shown to be Δ-universal by Halevi and …

With the rapid development of network and storage technology, cloud storage has become a
new service mode, while data sharing and user revocation are important functions in the …

Congruences are ubiquitous in computer science, engineering, mathematics, and related
areas. Developing techniques for finding (the number of) solutions of congruences is an …

It is well known that a congruence ax≡ b (mod n) has a solution if and only if, and, if the
condition is satisfied, the number of incongruent solutions equals. In 2010, Alomair, Clark …

In light of the vast number of existing cryptographic protocols, performance tradeoffs become
a major obstacle when selecting one for practical usage. For instance, protocols known to be …

We propose and implement a protocol for a scalable, cost-effective, information-theoretically
secure key distribution and management system. The system, called Distributed Symmetric …
