Network Mobility
What is Network Mobility
in Airplain or Train, so many nodes are there and they are connected to one router that is also moving. That means whole network is moving. We call it NEMO, Network Mobility.
What is Home Agent?
Because MN (Mobile Node) is moving, the location of the MN should be controled. HA (Home Agent)’s roll is that. (Should all MN must access HA at first? I’ll check it.)
RO (Route Optimization)
Let’s think an example. If there was an airplane in the USA, and now it is in the Korea and we try to visit an korean web site. Then the packets of MN must be delivered to USA at first, and then the packets are delivered to Korea because corresponding HA of the MN is in USA. We need to optimize the route path of the packets. Route Optimization means it.
The web motto, “Anyone can say anything about anything”
Nowadays people always want to communicate with others who are not only their neighbors or friends but also perfectly strange person on the Internet.
It is social networks.
I’m interested in social networks and it’s security issues.
without any limitations.
The rapid advance of network and communication technology make it possible.
What the attackers want
- Jokes
- Access control
- Personal information
- Company information
- Money
How to attack
- Spam
- Flaw in the third-party applications
- Worm
- XSS
- Plug-in
- Phishing
This paper is the greatest paper I’ve ever seen. Concise and clear expressions, a brilliant but modest idea are well-organized in only four pages (without figures) paper. A great paper always has not a complex and difficult idea but a simple idea, but I don’t have not only a brilliant idea but also just a good idea… T_T
Identity-Based Encryption (IBE) is similar with a public key cryptography. Most important difference is that IBE doesn’t need to exchange the certificates for each side. They can use other side’s identity as a public key. For Instance if Alice wants to send a message to Bob, Alice can encrypt the message by using Bob’s email address “bob@mail.com” as a Bob’s public key. Bob can decrypt the message by a private key corresponding to the public key that is issued by Key Generation Center (or Key Distribution Center, KDC).
I want to write a good… no, brilliant paper. At first, I need an idea. Yes, idea.
How to Write a Great Research Paper
Simon Peyton Jones, Microsoft Research, Cambridge
Writing a greate research paper is the hope of many researchers including me, but it is not easy. To me and to other researchers this slide note is quite useful and thanksful. Because it is not article or papre but a slide note, it is much more easy to read and understand. Most important thing to write a great research paper, however, especially in my case, is a great idea.
How to Write an Abstract
Phil Koopman, Carnegie Mellon University
An abstract is most important section of a paper because other researchers decide to read this paper or not by reading an abstract. Saying “My idea is quite brilliant!” is started from a good abstract. I have been difficult to write an abstract, so this paper is very thanksful.
Wireless Malware Propagation
This article’s subtitle is ‘A Reality Check’.Yes, it is about the reality in our works.
We researchers sometimes face the temptation of reality. Our works in the world of wireless networks are placed between theoretical possibilities and practical limitations. Changing arguments of a simulation into impractical values for better results or taking impractical assumptions to remove the weakness of proposed scheme is dishonest and must be rejected. In most case, however, it depends on the conscience of author. This article says about that point.
Honesty is the basic agreement to researchers, but I can understand that to be honest under every situation may be not easy. We, however, must keep this promise. This is obvious.
Logging in the Age of Web Services
It is the article of emphasizing the importance of log. According to this article, logging system is one of the most important clues that can predict or detect malicious attacks or system break down. Internet, however, is very large scale distributed system, so there are difficulties: when to log, where to log, what to log, and so on.
Frankly speaking, accountability is not familiar concept to me. It may be an abstract concept which is related with security issues. This article gives me a well-defined security issues that are really important today. Especially, I think the first capability, the ability to know the source of an arriving packet, is the most important point to defend DDoS attacks.
What capabilities should we expect of an accountable Internet?
- the ability to know with confidence the source of an arriving packet
- the ability to hold a user (or a machine) accountable for the traffic it originates
- the ability to determine what path an arriving packet has taken
- the ability to know the provenance of software updates arriving from the network and then authorize (or at least detect) any changes to software caused by arribing packets
Securing Online Games
Online game security is interesting issue. Hacking an offline game can be interesting issue to hackers, but it is just about the virtual economics. Hacking the traditional online games is similar to offline games’ case. Cheating caracters levels, virtual money, and items are just in the virtual world. Nowadays, however, virtual economics in the online game is strongly related with real economics. Users commonly trade their items, virtual money, and characters with real money.
Most of the today’s online games are massively distributed software, but security of massively distributed software is strongly related with the performance. Trade off between the performance and the security makes secure online games difficult.
