From isalekul at hotmail.com Tue Nov 1 20:38:13 2005 From: isalekul at hotmail.com (Salekul Islam) Date: Tue May 2 17:43:47 2006 Subject: [Avispa-users] General questions about the output Message-ID: Hi, I am trying to write the model of SPLICE/AS protocol. In expert mode, when I execute the OFMConly I have received the following attack: ATTACK TRACE i -> (c,3): start (c,3) -> i: c.s.N1(1) i -> (a,13): c.i.N1(1) (a,13) -> i: a.{a.c.N1(1).ki}_inv(ka) i -> (c,3): a.{a.c.N1(1).ki}_inv(ka) (c,3) -> i: c.s.{c.T(3).lt.{N2(3)}_ki}_inv(kc) i -> (a,13): i.c.x66 (a,13) -> i: a.{a.i.x66.kc}_inv(ka) i -> (i,17): N2(3) i -> (i,17): N2(3) Now, I have some questions: 1. Is this possible to get multiple attack traces (if they exist) for one specification? 2. What is the meaning of 3 in (c,3)? Does it mean the 3rd session or anything else? And why this number is dicrete like 3, 13,17..? 3. What is the meaning of 1 in N1(1)? 4. In this attack trace, the last two messages are quite redundant. Otherwise, this is a successfull attack. Anybody any clue about it? 5. Where can I get more information about the ourput of OFMC, ATSE and other tools? Thank you for your understanding. I am really interested in using AVISPA and I have found this one of the best tools for security protocols. Regards, Salekul -------------- next part -------------- An HTML attachment was scrubbed...

This is not possible as the tools stop the search at the first attack they find, and continuing the search might just result in lots of variants of basically the same attack. I recommend that you drop the goal that was found violated (e.g. authentication in one direction), to see if the other goals of the protocol do hold. > 2. What is the meaning of 3 in (c,3)?

These are also minor technical issues, sorry. (For question 3., the reason is to create unique terms for fresh nonces, and for question 4., the redundancy has to do with the attack predicates.) > 5. Where can I get more information about the ourput of OFMC, ATSE > and other tools? The manuals/guides that you can download as part of the avispa tool should contain all the information that is necessary to work with the tools, however if there are questions that are not addressed, the user forum is the right place to ask them. > Thank you for your understanding.

Given what you have said I assume you are using OFMC to see if the model is executable? The error message would suggest that some transitions in your protocol cannot be reached. You may be interested in the following code if you want to search for replay attacks (without the sessco option): role environment() def= ... composition session(a,b) /\ session(a,b) end role With regards my previous response I was not trying to sound patronising by suggesting you read the manual. It is a necessity, if you wish to be able to understand the tool. With reference to the notation (a,5) the letter refers to a role (eg. alice) and the number is a session number (in this case 5). The session number is used internally by AVISPA and you can simply ignore it.

I would recommend this if you plan to use the tool seriously. As for the messages you are receiving OFMC : SAFE CL-AtSe : SAFE SATMC : SAFE TA4SP : SAFE OFMC, CL-AtSe, SATMC and TA4SP simply refer to the backend in use. The online tool will attempt to execute your protocol with each backend in turn. If you download the tool it will come complete with documentation, which provides a good starting point for understaning the tool and will include further explanation.

The web interface should just be thought as a mode to get the feeling of the AVISPA tool. For instance, the resources (memory and time) assigned to each test are significantly limited on the web interface machine so to avoid memory swap and similar. A part from this, I would be interesting in knowing whether you have understood why the backends return different answers. If you have not, maybe you could share your HLPSL specification with us so that we can work together to understand the reasons.

When I give the command: ./avispa filename.hlpsl --ofmc At first, the HLPSL code was throwing attacks. But when I have just modified the intruder knowledge parameters (I removed a few parameters), the program was not responding (and after that the program crashes). I always get the following message: % OFMC % Version of 2005/06/07 SUMMARY Can anyone tell whats going on the backend of my machine. To tell you, I have like 60MB of free space on my hard-disk. Is this because of that or is it anything else going on.

It is not related to AVISPA itself, but rather my own research in the field of security protocols analysis. I'm developing a framework of tools and techniques with a purpose of supporting users wanting to utilize formal methods for security protocols analysis. The goal of the framework is to bring formal methods closer to practitioners, i.e. software engineers and designers. My own experience so far has been mainly with the CSP/FDR/Casper approach and, not surprisingly, AVISPA. Right now the framework is pretty much done, at least from the methodology standpoint (tool support is another story). Right now I'm preparing a usability study of the techniques I've prepared. I'd like to measure the usability characteristics of the framework such as relevance, usefulness, ease-of-use etc. using an approach derived from software quality management (I have a strong background in software engineering myself). For this purpose, I need an more-or-less independently derived set of requirements and evaluation criteria. And that is where you come in. I have prepared a small web-based survey which will allow me to recognize the expectations of users of a framework such as mine. Because the AVISPA community consists of individuals knowledgeable in the area and experienced with the technology, I would very much like to ask you to complete my survey. It consists mainly of "closed" multiple-choice questions and should not take you more than 10 to 15 minutes. The URL adrress for my survey is: http://kio.pg.gda.pl/iag/survey/ The survey form is processed by a free Reponse-o-Matic service. It's as anonymous as I could manage on a short notice: you don't have to provide or use your email address, no IPs are logged etc. Again, your help would be greatly appreciated.

The command avispa code.hlpsl --ofmc -sessco returns " the code is not executable" without giving additional information. This problem take place even with TLS.hlpsl giving as example in the avispa package. Thanks a lot. --------------------------------- Appel audio GRATUIT partout dans le monde avec le nouveau Yahoo!

I am experiencing the same issue with the web-interface as reported a few weeks back. I checked the mailing list and saw a thread that said: "During the night the machine used to run the AVISPA modules (back-ends and translator) crashed. We are re-started the machine and now it seems to work again. "We will try to investigate what happened to the machine and in any case we will monitor its behaviour. Please continue inform us if something weird happens." I think this has occured again. Can somebody please check into this?

Currently, the machine that hosts the backends and the translator is down and we're checking what's going on with it. A proper notice has been put online on the AVISPA web pages. We will inform you (and all the mailing list members) as soon as we fix the problem. Sorry, we apologize for this inconvenient. Best Regards, Jacopo. Jeffrey Kalvass wrote: > Hello.
