In modern cryptography, the secret sharing scheme is an important cryptographic primitive and it is used in various situations. In this paper, a timed-release secret sharing scheme (TR-SS) with information-theoretic security is first studied. TRSS is a secret sharing scheme with the property that participants more than a threshold number can reconstruct a secret by using their shares only when ...

Knowledge representation is a traditional field in artificial intelligence. Researchers have developed various ways to represent and share information among intelligent agents. Agents that share resources, data, information, and knowledge perform better than agents working alone. However, previous research also reveals that sharing knowledge among a large number of entities in an open environme...

W e analyze the value of and interaction between production postponement and information sharing, which are two distinct strategies to reduce manufacturers’ uncertainty about demand. In both single-level and two-level supply chains, from the manufacturer’s perspective, while information sharing is always valuable, production postponement can sometimes be detrimental. Furthermore, the value of p...

Passenger information aims at improving the user-friendliness of public transport systems while influencing passenger route choices to satisfy transit user’s travel requirements. The integration of transit information from multiple agencies is a major challenge in implementation of multi-modal passenger information systems. The problem of information sharing is further compounded by the multi-l...

This article presents a survey of authorization models and considers their 'fitness-for-purpose' in facilitating information sharing. Network-supported information sharing is an important technical capability that underpins collaboration in support of dynamic and unpredictable activities such as emergency response, national security, infrastructure protection, supply chain integration and emerg...

Abstract Taking the sharing economy as an example, article discusses social basis for development of internet platform. It shows that and platform not only benefits from its economic efficiency but also relies on technological dividends constructed by technical characteristics application, which have expanded beneficiary groups broadened new technology.

Cost-sharing rules for paying physicians have been advanced as a way of generating incentives for the provision of quality care, while recognizing their potential negative effects on production efficiency. However, the optimal sharing rate typically depends on the degree to which the physician acts in the interest of the patient, what we identify as the physician's altruism. Since the degree of...
