Strongly Unforgeable Signatures and Hierarchical Identity-Based Signatures from Lattices without Random Oracles
Abstract. We propose a variant of the “bonsai tree” signature scheme, a latticebased existentially unforgeable signature scheme in the standard model. Our construction offers ...

An optimistic fair exchange protocol and its security in the universal composability framework
: Fair exchange protocols allow both or neither of two parties to obtain the other's items, and this property is essential in e-commerce. In this paper, we construct an optimi...

Efficient Protocols for Signing Routing Messages
In this work, we aim to reduce the computational costs of using public-key digital signatures in securing routing protocols. Two protocols (COSP and IOSP) using one-time digitalsi...
