Cryptography traditionally used the names Alice and Bob to refer to two parties who want to communicate securely over an insecure channel. Eve is the traditional name of someone who wishes to intercept and read their communications. I have come across a good link on the Internet about the traditional names in Cryptography scope. A few important names are below:
- Alice and Bob. Generally Alice wants to send a message to Bob. These names were invented by Ron Rivest for the 1978 Communications of the ACM article presenting the RSA cryptosystem. (The 1977 technical report on RSA did not use these names.) Rivest denies that these names have any relation with the 1969 movie Bob & Carol & Ted & Alice as occasionally suggested by others.
- Carol, as a third participant in communications. Thereafter, we often have Dave, a fourth participant, and so on alphabetically.
- Eve, an eavesdropper, is usually a passive attacker. While she can listen in on messages between Alice and Bob, she cannot modify them. In quantum cryptography, Eve may also represent the environment.
- Isaac, an Internet Service Provider (ISP).
- Ivan, an issuer (as in financial cryptography).
- Justin, from the justice system.
- Mallory, a malicious attacker; unlike Eve, Mallory can modify messages, substitute her own messages, replay old messages, and so on. The problem of securing a system against Mallory is much greater than against Eve. The names Marvin and Mallet can also be used for this role.
- Matilda, a merchant (as in ecommerce or financial cryptography).
- Oscar, an opponent, is usually taken as equivalent to Mallory.
- Pat, see Peggy.
- Peggy, a prover, and Victor, a verifier, often must interact in some way to show that the intended transaction has actually taken place. They are often found in zero-knowledge proofs. Another name pair sometimes used is Pat and Vanna (after the host and hostess on the Wheel of Fortune television show).
- Plod, a law enforcement officer (P for police, also "Officer Plod" from the children's TV show Noddy).
- Steve, sometimes used in reference to Steganography.
- Trudy, an intruder: another alternative to Mallory.
- Trent, a trusted arbitrator, is some kind of neutral third party, whose exact role varies with the protocol under discussion.
- Walter, a warden, may be needed to guard Alice and Bob in some respect, depending on the protocol being discussed.
- Zoe, often the last party to be involved in a cryptographic protocol.
Am I a stand-alone person? #Submitted by hurryon @ 03-23 [12:54 pm]
Are you a stand-alone person? If someone ask me like that, I will hesitate in speaking. Honestly, I always depend upon for another. It is true. When I was in London, I turned to her. I couldn't do anything without her. Now? I turn to him in the lab. He has been helping me to prepare a lecture and a project. In the lab, I am a leader of two projects in this year. However, I couldn't do anything without his helping.
I was told at one time that people get old and they need to another people's helping. It is definitely right. When I was young, I was always do everything without any consultation. I believed that I was alone so I didn't have to turn to anyone, but I am now not. I will never walk alone. Well...I am not a stand-alone person, but I have a xinetd-person, who can control and manage many people efficiently, and I am doing a effort to know what is my job. Ultimately, I will be a xinetd-person.
I decided to translate the book. #Submitted by hurryon @ 03-22 [06:56 pm]
Well...I will have translated a book in this year. The book's title is "AAA and Network Security for Mobile Access: Radius, Diameter, EAP, PKI and IP Mobility". The book is the first book published about AAA in the world and the authors have been active in the standardization of mobility and security procedures in IETF, 3G and IEEE since 2000 and are coauthors of a few IETF RFCs. The book's content is also wonderful and fantastic as well.
I have contacted to get translation rights with John Wiley & Sons, Ltd., which is one of the best publisher in science, and I was permitted from my adviser. Fortunately, he gived me the chance. Now I have got to work free from care. I now feel a feeling of well-being.
Yes, I am inclining toward the modeling and performance analysis. #Submitted by hurryon @ 03-20 [12:09 am]
As you know I am not an expert at mathematics. My mathematics are weak, but I want to be an expert at modeling and performance analysis. It shoud be one of goals every computer scientists. Although a little too late, I have decided to start it. I know it might be an endless study. Recently, I have been reading books related mathematics, probability, and queuing.
In this month, I am writing a paper related performance evaluation in wireless networks. Before I studied the books, I couldn't know how to evaluate the model, which I had suggested in the paper, and when I had read the papers including the performance evaluation about the scheme of the papers, I had been afraid of reading them. Now? I am not. Now, I try to find papers including the performance evaluation to analyze them. It is a good way to study, isn't it?
It is my wish list on Amazon.com. #Submitted by hurryon @ 03-14 [06:03 pm]
As kids, I've got my wish list. Even though I can't buy that now, I add the items to the list. Do you remember? One of my dream is that I want to have my own library in my house. You can see Jong-Hyouk Lee's entire wish list at ![[http]](/imgs/http.png) here. The books might be in the library and I've read them before I pass away.
Phew...Anyway, it's time to pass the English exam. @.@;;
Do you have any issues? #Submitted by hurryon @ 03-14 [05:49 pm]
Basically, everyone says yes. However, you have to know the mission is considered one of the critical job in your lab. Your colleagues are undergoing the most radical changes in their life like you. You are not alone. I know. I understand your situation, but you must forget.
Just, stick with your job. Hang on your position. It's the easiest way.
I took on a teaching assistant role. #Submitted by hurryon @ 03-07 [09:27 pm]
Well...I unexpectedly took on a teaching assistant role for Computer Engineering Experiment class. So I hurriedly wrote a syllabus for the class and made the schedule. The class time is Thursday, 18:00 - 21:45. I know it will be a great burden for me. I have a lot of things to do so I am not sure I can teach them hard.

I have not seen someone who is a great help to me. Where are you? I couldn't talk over the telephone although I tried to call many times. What's up?
Yesterday was her birthday. #Submitted by hurryon @ 03-06 [09:35 am]
I couldn't give anything. We were just together. Is it enough? Honestly, I couldn't do about her birthday. I know. I know. I can't do anything. If I were minted, I wouldn't feel like this. Phew...hurryon...It's getting on my nerves. Please, stop it!!!
The plan for my mother and father. #Submitted by hurryon @ 03-03 [02:45 pm]
I am seeing the picture my mother and father took in Jeju. I can feel they were happy, but one of them dosen't exist anymore. I also can know another person in the picutre aches for him. I'm as well. I thought What I can do for her. She is fatigued and leads a lonely life.
I decided I will take a trip with her before I get employed. I will come by the place they went. Even though he can't go together, I believe he will feel so good in Heaven.
How do I adapt session key reuse approaches. #Submitted by hurryon @ 03-03 [01:31 pm]
Well, this week I'm reading some papers are about session key and its reuse approaches. You know they are probably useful approaches to reduce an authentication time. One of the approaches uses an old access router to get the session key of a new access router. This approache is obviously simply. Too simple.
Now I am thinking how I can adapt the seesion key reuse approaches on a ping-pong effect or in an inter-authentication problem in wireless networks. To resolve the ping-pong effect. To reduce the authentication time of the mobile node. To give the mobile node enough time. To improve the security in wireless networks. Phew...These problem makes me hungry.

You know I am currently a M.S. candidate. It means that I can't care about me. I've taken a picture. As you see, it's messy...it's dirty...it's filthy...but it's my desk. I am happy. Although someone can put me aside due to my lowly appearance, I don't care. I have my family believe me and my lover. Moreover, I've known after I came back to the lab that they need me. What shall I need more?
It just needs to sweep! That's all!
