The introduction of verifiable computation came as a result of the increasingly common phenomenon of "outsourcing" computation to untrusted servers and also to the growing desire of weak clients to outsource computational tasks to more powerful computation services like in cloud computing. Verifiable computation enables a computer to offload the computation of some function, to other perhaps...
Nowadays people can easily use any smart device at hand to capture scenery and then upload it to the cloud storage. Cloud storages are widely used for storing the generated multimedia content. However, the risk of potential private data leakage may exist since cloud storages are normally in a public domain. To enhance the security and privacy of images on the cloud storage, we proposed an integrated...
In order to resolve problems such as server's weight described inaccurately, load balancing schedule inefficiently and so on, which exist in the traditional load balancing algorithms Based on server cluster, a kind of adaptive weighted least-load balancing algorithm is founded in this article. The server nodes are divided into mild load nodes and non-mild load nodes. The servers are polled in the...
Because the traditional modes of identity authentication have security flaws and can not meet the practical requirements of network safety. Based on the traditional modes of identity authentication, this paper presents a new design of bidirectional identity authentication solution which combines PKI with fingerprint features, provides the concrete structure of it and certification process, this solution...
This paper introduces the design and implementation of HTTP proxy server based on real-time link. The real-time link packages UPLink and PSLink into a link. The UPLink is the link between user and proxy server, and PSLink is the link between proxy server, and target server. These two links exist and close together, and it can solve the problem of link's closed incompletion. This approach can reduce...
In structured P2P networks, the heterogeneity of node capacity, the skewness in query pattern and the greedy routing strategy could result in the load imbalance problem. However, existing load balancing algorithms for structured P2P networks mainly focused on handling the heterogeneity among nodes and the skewed workload. To deal with the load imbalance issue caused by the greedy routing strategy,...
Due to the soaring of knowledge-based economy and the blooming growth of e-business, the way to effectively accumulate and manage valuable data of knowledge has become an important issue for all the industry. There are many knowledge management systems built for large corporate companies. However, not many open source systems are available for small research communities. Currently, Wiki has not only...
Botnet has recently been identified as one of the most important security threats of the Internet. So we should study the new technology which may be used by botmaster in the near future. In this paper we predict the new feature of the next generation botnet and present the design of an advanced P2P botnet basing on our discussion.
