Multi-pixel encoding is an emerging method in visual cryptography for that it can encode more than one pixel for each encoding run. Nevertheless, in fact its encoding efficiency is...
A recent publication introduced a Visual Crypto (VC) system, based on the polarisation of light. This VC system has good resolution, contrast and colour properties. Mathematically,...

Abstract. We propose a micro-payment scheme for symmetric multihop cellular networks that encourages intermediaries to transmit packets and recipients to provide auditing informati...
In an optimistic approach to security, one can often simplify protocol design by relying on audit logs, which can be analyzed a posteriori. Such auditing is widely used in practice...
At Crypto'07, Goyal introduced the concept of Accountable Authority Identity-Based Encryption as a convenient tool to reduce the amount of trust in authorities in Identity-Bas...
