A nonce is a cryptographic input value which must never repeat within a given context. Nonces are important for the security of many cryptographic building blocks, such as stream c...
We show that every construction of one-time signature schemes from a random oracle achieves black-box security at most 2(1+o(1))q , where q is the total number of oracle queries a...
Wireless sensor network (WSN) commonly requires lower level security for public information gathering, whilst body sensor network (BSN) must be secured with strong authenticity to...

We present ShMAC (Shallow MAC), a fixed input length message authentication code that performs most of the computation prior to the availability of the message. Specifically, Sh...
In this paper, we take a closer look at the security of outsourced databases (aka Database-as-the-Service or DAS), a topic of emerging importance. DAS allows users to store sensit...
