Publication of an llvm-based tool that protects against fault injection attacks
Hello,
My team and I have recently published an LLVM-based tool at
“Cryptography and Security
in Computing Systems 2016” (CS2), and we would like to add it on the
list of LLVM related publications.
The goal of our tool is to automatically protect the code being compiled
against fault injection attacks

[LLVMdev] own source transformation
Hi,
I'm a student who is going to make a countermeasure for dangling pointers in c for his thesis.
I need to make my source transformation using llvm. Nobody in my university already used LLVM.
I already read a some documentation about llvm but i'm still lost.
Do there exist some " examples/Tutorials" for making small source transformations.
Or is there somebody who can help

openssh and keystroke timing attacks (again)
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

Winbind offline cache and strangeness...
The version of samba that comes with Ubuntu 16.04 is very old (4.3.11) and
the offline login feature for winbind simply doesn't work. I'm not sure if
it's fixed in newer versions or not as I'm still on Ubuntu 18.04 (samba
4.7.6) which also doesn't work. If you are only using it to authenticate
to an AD controller, you should switch to using sssd. I have multiple
clients that

Security of OpenSSL ECDSA signatures
Dear OpenSSH devs,
I came accross this paper yesterday. http://eprint.iacr.org/2011/232
It states that they were able to recover ECDSA keys from TLS servers by
using timing attacks agains OpenSSL's ECDSA implementation.
Is that known to be exploitable by OpenSSH ? (In my understanding, it's
easy to get a payload signed by ECDSA during the key exchange so my
opinion is that it is).

Winbind offline cache and strangeness...
I've setup a portable system (ubuntu 16.04) joined to my AD domain,
that in their primary network works as expected.
But in this 'COVID time', the portable start to roam around, and users
say me that, suddenly after some days of use, get incredibly
sloooowww... after that users reboot, and cannot get back in, login
refused.
I've setup a VPN, but clearly if users cannot login

GSOC 2011 : Weighting Schemes
Hi All,
I'm Sumith, a postgraduate student in Monash university. I'm working in the
area of Text weighting schemes and Text Mining. When I'm going through the
GSOC project list, I felt interested in the 'Weighting Schemes' project. At
the moment, I have worked with different weighting schemes as TF-IDF and
would love to join and contribute with my ideas in this project.

Announce: OpenSSH 9.6 released
OpenSSH 9.6 has just been released. It will be available from the
mirrors listed at https://www.openssh.com/ shortly.
OpenSSH is a 100% complete SSH protocol 2.0 implementation and
includes sftp client and server support.
Once again, we would like to thank the OpenSSH community for their
continued support of the project, especially those who contributed
code or patches, reported bugs, tested

If there isn't any reason then I'd like to send in a patch adding support for
those weighting schemes in weight.cc and I agree omegascript

GSoc Project Idea Weighting Schemes (Ranking)
Hi,
I am Abhishek
Currently Xapian::Weight follows BM25 scheme, many models such as the
Divergence from Randomness (DfR) family of models, Unigram Language Model
and the Bi-gram Language Model implemented two years ago in GSoc 2012 yet
not merged to the master.
The new weighing schemes or improvement in implementing the previous models

GSoC 2015 - Weighting Schemes
Hello everyone!
I'm Ayush Tomar, junior undergrad in Computer Science from New Delhi,
India. I love C++ coding and working on machine learning and information
retrieval project. I was exploring the GSoC ideas for Xapian and the
project on "Adding Weighting Schemes" looked really interesting to me. I
wanted to work on text mining/IR this summer and this idea seems perfect!

Weighting Schemes
Hi!
I am Praveen Kumar, an Applied Mathematics student and I am interested in
developing other weighting schemes for Xapian through GSOC.
I did not have any formal course in Information Retrieval in our institute.
The theory that I presently know is
from the Xapian documentations and other references and resources mentioned
on the website which I read
to design our own Probabilistic Information

Xapian now has Divergence from Randomness schemes
Hello guys, you'll will be happy to know that the current codebase now
includes the divergence from randomness weighting schemes which are known
to outperform a lot of known weighting schemes such as BM25. Thanks to the
amazing mentorship of Olly Betts and Dan Colish, our search results will
now be better than before and Xapian will be more preferred in the research
community than it was
