Multi-exponentiation is very important in varies cryptographic and digital signatures. In the situation like electronic cash and SNS websites, the server need to answer a mass of requests in a short time. With every request, there are always processes of encryption, decryption, signature and verification. In these processes, there are large amount of computations of multi-exponentiation, which shows...
Linear (k,n) secret sharing scheme is a class of (k,n) secret sharing, where all the n shares of a secret satisfy a linear relationship. It plays an important role in other cryptographic systems, such as multi-party computation and function sharing schemes. On the other hand, cheating problem in (k,n) secret sharing is an important issue, such that cheaters (dishonest players) submit forged shares...
Recently, the TV landscape is rapidly shifting from the traditional “laid-back” experience to a “lean-forward” multiscreen experience. In this paper, we propose MUTAS (MUltiscreen TV experience As a Service), a novel cloud-based service delivery model, in response to this trend. The design objective is to facilitate the development process of new multi-screen features, and improve user experiences...
Deadline assignment is to assign each subtask composing a distributed task with a local deadline such that the global deadline can be met. Today's real-time systems often need to handle hundreds or even thousands of concurrent customer (or service) requests. Therefore, deadline assignment is becoming an increasingly challenging issue with a large number of parallel and distributed subtasks. However,...
Social tagging has become a popular solution for recognition and management of resources in web2.0 era. To solve the current problem of insufficient capacity of semantic description of web services, a multi-dimensional social tagging method for semantics of web services is proposed. Under the guidance of general social tagging model, users will annotate services manually from the domain the services...
A new type of heat-fading-resistance semimetal friction materials was prepared though changing traditional bond. The influences of a new high-performance bond on the semimetal friction materials were researched by way of contrastive experiments using different bond. The good performance of this bond is proved. According to the analyze of the experiment done in the defined rapid wear and rear machine,...
In this paper, a newly vision-based localization method for mobile robots is presented. The cost of hardware for this localization system is very low. Based on background subtraction and optical flow tracking, the presented method overcomes the shortcoming of general background subtracting method- being sensitive to noises and interferences of other mobile objects. Besides, the presented method is...
