similar to: Defeating Timing Attacks

Hello, In response to the timing analysis attacks presented by Dawn Song et. al. in her paper http://paris.cs.berkeley.edu/~dawnsong/ssh-timing.html we at Silicon Defense developed a patch for openssh to avoid such measures. Timing Analysis Evasion changes were developed by C. Jason Coit and Roel Jonkman of Silicon Defense. These changes cause SSH to send packets unless request not to,

I'm reading this fine article on O'Reilly: http://linux.oreillynet.com/lpt/a//linux/2001/11/08/ssh_keystroke.html <quote> The paper concludes that the keystroke timing data observable from today's SSH implementations reveals a dangerously significant amount of information about user terminal sessions--enough to locate typed passwords in the session data stream and reduce the

Nicolas, The timing attack described in the paper by Dawn Song et al. works by examining the timing of keystrokes. Currently OpenSSH sends a packet every time you press a key, thus it is possible to capture the approximate inter-keystroke timing of a user (they found minimal overhead in time from a key press to packet sent). Our patch causes a packet to be sent every 50 ms regardless of whether

The ruby code in this isn''t evaluated... flash[:notice] = "Your last recorded entry was <%= @in_out.time_in %> <br />You are currently marked as ''In'', you probably want to check ''Out''" Is there a way? Craig

Can anybody tell me how to pass a variable from the rake command to my steps file using cucumber? I have the following in my Rakefile: ## Rakefile Cucumber::Rake::Task.new do |t| profile = ENV[''PROFILE''] || ''default'' browser_type = ENV[''BROWSER''] || ''*chrome'' t.cucumber_opts = "--profile #{profile}" end I

I am utilizing an openssh tunnel between two Linux boxes. On the client box I issue the following commands to set up the tunnel; - ssh -w0:0 root at x.x.x.x -v where x.x.x.x is the IP address of the Linux system running sshd - ip addr add 10.0.5.1/32 peer 10.0.5.2 dev tun0 - ip link set tun0 up On the box running sshd I issue the following commands: - ip addr add 10.0.5.2/32 peer 10.0.5.1 dev

In my view code, I have <%= datetime_select "in_out", "time_in" %> which returns in params :in_out: !map:HashWithIndifferentAccess time_in(1i): "2006" time_in(2i): "6" time_in(3i): "12" time_in(4i): "20" time_in(5i): "24" and I want to save that datetime to a column in the db... if

Hi all, Over the past 10 years, there has been some discussion and several patches concerning keystroke timing being revealed by the timing of openssh packet network transmission. The issue is that keystroke timing is correlated with the plaintext, and openssh users expect their communications to be kept entirely secret. Despite some excellent ideas and patches, such as Jason Coit's

Hi, 2.2.33.2 Well your confs are almost mine except for director_ping_idle_timeout = 30 secs submission_relay_max_idle_time = 29 mins but i think they're not imap related (i may be wrong) any other hint why is this happening? I was used to the old IMAP server than dovecot, where emails appear in the inbox, no matter if it was selected for 15m or the last 4 hours Any ideia please let me

Awesome! Thanks so so much! I'm very interested in doing some work with compilers. Yeah, I'm considering writing a research proposal where I work for JIT-SFI, SFI Evasion Technique and Mitigation, and a few other things. Considering your experience working on modifying llvm, what would you say would be a topic where I could start out doing some good work on, either in a new direction or

I find that for most applications, having managed="Y" is best, but for some applications I'd like to be able to launch them managed="N". I've been googling and it seems that in the past this was possible with a command line parameter, but it seems that this is no longer available. I'm using the 20050524 (i think) version of wine. Is there anyway for me to launch

man_in_shack banned me during a casual conversation where i was explaining my dual x server wine setup, saying I was contradicting myself. I obviously wasn't trying to contradict myself, if I did, and I don't see how this is ban-worthy under any circumstance.

Dear all, I have some difficulty getting R-1.3.0 to run on the alpha, with osf4.0e (Tru64, or whatever they call it... :-) ). configure reports the following configuration: R is now configured for alphaev6-dec-osf4.0e Source directory: . Installation directory: /astro/local C compiler: gcc -mieee -g -O2 C++ compiler: c++ -g -O2 FORTRAN

I read a lot of white papers, but is there not any open source implementation of SFI or artificial diversity? I google around, but I can't find anywhere anything regarding what I could openly download. In the same respect, I would also like to make an innovation proposal to create such an endeavor if there is not one already. -------------- next part -------------- An HTML attachment was

Hello all, I am wondering where one would submit a patch to OpenSSH cvs version? I have written a patch that allows the user to set a timeout the ssh clients connection attempt. I added this because many of us use ssh in automated scripts and in some cases machines may no longer be reachable, rather than wait you can set the timeout to say 3 seconds (-z switch). -- Larry Cashdollar

Hello there, complete off-topic, sorry about this, but my former idea was to install a CentOS on an old mac mini (PPC!). Disappointed to see that PowerPC is not a supported architecture and that non ARM or Intel architecture are not managed by recent distros.. :-(. Searching the web, I see very few possibilities to install a recent (I need gnome2) GNU/Linux distro on such hardware. I gave Linux

hi, all I do a hotplug detach a network in a thread, because virDomainDetachDeviceFlags maybe asynchronous, so I do like follow: cb_para->cluster_id = info->cluster_id; cb_para->group_id = info->group_id; cb_para->vsys_id = info->vsysid; cb_para->vnf_id = info->vnf_id; cb_para->conn = conn; cb_para->time_out = 20*1000;//20s
