Something about my proposal

I chose Android, because I really interest about , about open-source, about Linux, about Google and moblie device. How can I find out the way to link them together, then I found Android.

From the software developer (for example my major), Android is use Java language, the base is Linux,  it’s a good way to see that, means we have more things to control. Is it that true?

Anyway, I will try to do some research from web, from books and other way, like do some experiments, maybe I will try to create the application on Android. Do as many as I can.

Proposal

Area:

My interesting area is Open Source. I’m interested in Linux, try to use Ubuntu instead of Windows, especially interested in using and developing the linux system on mobile device, like Google Android.

Topic:

Nowadays, because Google and some companies, like Canonical, they develope and support  linux, so  it’s more and more popular than before now, more and more people use it, but still just a small part, especially in desktop market, just got 1%.  In mobile system market, have Windows mobile, iphone system and Android. From a developer, we know Windows mobile and iphone system they don’t like Android open all the code for the developer who want to open application or even though which company can use it to change and have a new one. As a new system,  Android not just used in smart phone, also the companies try to use in Digital TV-Set Top Box and Netbook. I think it can be more and more popular. Because of that, it can give programmer more choose, more freedom to develop the system. All the things just begin now.

Question:

I would like to know in the future, is it Android will be a famous mobile system for the programmers in the world or just because Google and then famous for a while after just nothing special?

Providing Security and Privacy through Context and Policy Driven Device Control

link: http://www.w3.org/2008/security-ws/papers/ibm-in-policy-driven.pdf

Summary:

Nowadays, as the computers and cell phones price goes down, more and more people can have, they become the important things in our lives. Internet connects everything together.

This paper describes an approach that integrates declarative policies, context, OS level device control, and existing carrier authentication techniques to control access to features of mobile devices for web applications. The approach builds upon a body of existing work and adapts it to the mobile handset scenario.

In the paper, the author proposed a system that leverages carrier authentication / signon process, and combines it with context dependent, policy driven security mechanisms to control access to device features from web applications. Also show that can be combined with I/O control mechanisms in the OS kernel to enforce these policies.

He notes that such mechanisms can also control access to the context related data on a device. For instance, consider a shopping scenario where a person entering a store has a shopping list. Sharing this information with a store might be related to what store it is, or perhaps what it offers (discounts) in exchange. Since a file can be treated as a device, the I/O control mechanisms can be used to share/show or hide a file based on context as well.

Such a combination of integrated device and data control will be an important underlying mechanism for enabling sophisticated web based applications on mobile devices.

a) What is the title and what does the title tell you about the paper?

The title is “Providing Security and Privacy through Context and Policy Driven Device Control”.

From the title, I know it’s talking about how to provide the security and privacy to the policy driven device when control them.

b) Who is the paper written by and do they seem credible to you?

This paper was written by Anupam Joshi. He works in IBM India Research Labs.

Anupam Joshi is a Professor of Computer Science and Electrical Engineering at UMBC.

From this reason it’s credible to me.

c) Does it have a helpful abstract? Give reasons for your answer.

Yes, it does.

The author gave the introduction and background, then put forward some problems, after that, had the solution and the instance.

d) What did the author(s) do in their research and what did they find?

They looked at policy driven security.

Solution:

The first is an authentication and identity management system in which trust can be grounded.

The second component is a policy system.

The third critical component of such a system will be the actual security mechanism on the device.

e) Was the paper was worth reading? Give reasons for your answer.

It was worth for me, I’m interesting in this part of area, and it’s good for me to understand it.

f) Do you believe the results/findings or the paper? Give reasons for your answer.

Yes, I do.

It’s very important to protect the Policy Driven Device, nowadays. People do many things just try to improve the system security. It’s also making a sense to me.

g) What form of research approach did the researchers follow and do you think this was a useful approach?

Chose existing case. For example, he chose Android to explain and a schematic of the Context and Policy driven access control system. Also have the experiments. From these, it’s a useful approach I approve.

h) What did you learn from reading the paper?

This paper gave me the information what I want to know, it’s including the area I would like to learn, about the security and privacy. I didn’t learn a lot from it, not get in very deep, but it let me know the general point, I appreciate.

The Eucalyptus Open-source Cloud-computing System

Summary:

From this paper, I know something about what’s the EUCALYPTUS (Elastic Utility Computing Architecture for Linking Your Programs to Useful Systems) Open-source Cloud-computing System, the Eucalyptus infrastructure which began as a University of California Santa Barbara project in 2007 and allows enterprises to deploy large-scale on-premise private clouds as well as hybrid clouds that use both private and public resources. The system is built to allow administrators and researchers the ability to deploy an infrastructure for user-controlled virtual machine creations and control existing resources.

Most cloud computing systems in operation today are proprietary, and rely on allocated resources. This limits their capacity for research.  The authors of the EUCALYPTUS system decided to build an open-source software framework for cloud computing that implements what’s commonly referred to as “Infrastructure as a Service”.

The EUCALYPTUS system is web based and has been designed as a modular system where components may be replaced or enhanced in order to foster future cloud computing research efforts. When designing the system, the authors had a difficult job as they needed to consider users’ permission, security, and the requirements of the instance manager (IM), group manager (GM) and cloud manager (CM).

However, once operational the EUCALYPUTS system maximises the capacity of existing resources for research.

a. What is the title and what does the title tell you about the paper?

The title is “The Eucalyptus Open-source Cloud-computing System”. From the title I know it discusses how to use open-source to build a Cloud-computing system.

b. Who is the paper written by and do they seem credible to you?

This paper is written by Daniel Nurmi, Rich Wolski, Chris Grzegorczyk

Graziano Obertelli, Sunil Soman, Lamia Youseff, Dmitrii Zagorodnov.

I checked their credentials, experiences on the Internet, they work in University of California Santa Barbara and are the people working on this project-EUCALYPTUS. They’re credible to me.

c. Does it have a helpful abstract? Give reasons for your answer.

Yes, it does. The abstract does a good job.

First, the abstract introduces what is a cloud computing system, and provides a lot of information and examples which are easy to understand.

Secondly, discusses alternative systems. Some are good, but most are proprietary and the users don’t have the ability to control them.

Finally, informs me of how the authors have designed and built the project called    EUCALYPTUS, which really gives users the ability to run and control what they want.

d. What did the author(s) do in their research and what did they find?

The authors found weakness in cloud computing systems.

1. Nowadays, most systems in operation are proprietary or depend on software    and the system allocation. So Researchers interested in pursuing cloud-computing infrastructure   questions have few tools with which to work.

They have done the experiment from they’re research. For the result they found, users don’t have enough freedom when they using the cloud-computing system, so the authors try to change.

They found these questions and tried to build the right thing.

e. Was the paper worth reading? Give reasons for your answer.

Yes, it was. I learned a lot from it.

I now know what is different between normal cloud-computing and EUCALYPTUS. The authors built the system and present a new method of cloud-computing.  I understand how they developed the system and the difference between users and managers. In the system have three levels of managers, now have the ability through a secure system to control and allocate resources more efficiently to users as they are required.

f. Do you believe the results/findings or the paper? Give reasons for your answer.

Yes, I do.

First, I found it from the Google’s scholar. Second, it looks credible to me. Third, the authors provided details, the advantage and disadvantage, discusses the things which are improving, how to improve.

g. What form of research approach did the researchers follow and do you think this was a useful approach?

Mostly from the experiment, also has from the books, internet, and people. Because that they have the proof to prove the result. What I think the approach was quite good, not just use one way, that can’t let you know and prove enough. The authors they collected the information what they want from many ways, this is excellence.

h. What did you learn from reading the paper?

From this paper, I knew about the disadvantage in cloud-computing systems and why is disadvantage. Know the EUCALYPTUS improves the open-source cloud-computing system, and is helping to provide the research community. It makes clear me about the cloud-computing I stuck on it. Conscious then if want to improve thing need to do a lot, it gave me so much information I want.
