Nowadays cloud computing is becoming more and more popular. As it saves cloud user the budget to purchase relatively expensive and easily outdated hardware and the energy to maintain system, some compromises comes along as well, such as computing environment and stored data out of control, which put cloud user on the horns of a dilemma. In order for cloud users to have more faith with the security of computing environment and data on the remote uncontrolled cloud, trust should be build between them. It's easier to trust when you can verify. We took advantage of sealed storage of trust computing to improve traditional trust chain technology in order to provide a dual verifiable trusted bootstrap to make sure each compartment during system bootstrap not to be maliciously changed. We extend trusted chain to memory by developing monitoring tools in privileged domain using features provided by virtual machine monitor to monitor and record runtime states of security critical application in targeted virtual machine instance. Measurements of system configurations stored in platform configuration registers of TPM along with runtime states of application in cloud user's vm are reported to corresponding cloud user through remote attestation which is a key feature of trusted computing as well in order to provide genuine evidences to cloud user.
如今,云计算正变得越来越流行。在为云用户节省了购买相对昂贵且容易过时的硬件的预算和维护系统的精力的同时,也带来了一些妥协,例如计算环境和存储数据失控,这使云用户处于两难境地。为了让云用户对远程不受控制的云上的计算环境和数据的安全性有更多的信心,需要在云用户和云用户之间建立信任。当你能证实时,就更容易信任。我们利用信任计算的密封存储对传统的信任链技术进行改进,以提供双重可验证的可信引导,确保系统引导过程中的每个分区不被恶意更改。我们利用虚拟机监视器提供的特性,在特权域中开发监视工具,将信任链扩展到内存,以监视和记录目标虚拟机实例中安全关键应用程序的运行时状态。通过远程认证将存储在TPM平台配置寄存器中的系统配置测量值以及云用户vm中的应用运行时状态报告给相应的云用户,这也是可信计算的一个重要特征,从而为云用户提供真实的证据。

A probability based adaptive multicast routing scheme for delay tolerant networks 时延容忍网络中一种基于概率的自适应组播路由方案
Pub Date : 2011-12-01 DOI: 10.1109/ICCIAUTOM.2011.6183998

Many Delay Tolerant Networks (DTNs) applications need multicast service, thus making efficient multicast communication support essential. In this paper, we propose a Probability-based Adaptive Multicast Routing scheme (PAMR) to address the challenges of intermittent link connectivity and frequent partitions in DTNs. PAMR relies on node encounter histories rather than the global knowledge or the summary of link states of the network topology, which makes PAMR be more flexible and practical than the existing multicast routing schemes. Furthermore, PAMR can handle different DTNs application scenarios by adjusting network parameters. Extensive simulations have been conducted to verify the performance of PAMR and the results indicate that the PAMR scheme can achieve a higher bundle delivery ratio and incur much smaller end-to-end delay at the cost of comparatively lower delivery efficiency.
许多容忍延迟网络(DTNs)应用需要组播服务,因此有效的组播通信支持是必不可少的。在本文中,我们提出了一种基于概率的自适应组播路由方案(PAMR)来解决DTNs中链路间歇性连接和频繁分区的挑战。PAMR依赖于节点相遇历史,而不是网络拓扑的全局知识或链路状态的总结,这使得PAMR比现有的组播路由方案更加灵活和实用。此外,PAMR可以通过调整网络参数来适应不同的dtn应用场景。大量的仿真验证了PAMR方案的性能,结果表明PAMR方案可以实现更高的束投递率,并以相对较低的投递效率为代价产生更小的端到端延迟。

A fuzzy clustering recognition method is proposed to identify cells from sliced marrow cell image. In our image processing, leukocytes can be distinguished against other cells like red cell, megakaryocyte, and cytoplasm. The leukocytes can be further distinguished into promyelocyte, myelocyte or metamyelocyte. Probably the ratio of the counts of these three kinds of leukocytes can be used as the indication of leukemia relapse. Previous work on this project involves the recognition using pixel distribution and probability lays the background of data processing and preprocessing. Constraints based on size, pixel distribution, and grayscale pattern are used for the successful counting and positioning of individual cells. This shape, pattern and color based method can reach satisfied counting and we hope it can be used to get the relative positions for the research of pro-ALIP structure.

Using the virtual displacement of missile in short time, established a 3-dimensional variable structure guidance (VSG) logic with terminal angle constraints for un-powered homing missile. Then contrasted the trajectories, control angles and loads of the missile with VSG and PNG (proportional navigation guidance) command order, and the simulation results showed that the designed guidance logic not only could make sure the missile impact the target in specified direction precisely, but also make sure the final control angles close to zero. So the designed guidance law adapted to the homing missile to attack ground target precisely with terminal angle constraints.
