256-bit AES Encryption for SSL and TLS: Maximal Security

Wednesday, February 4th, 2015

SSL and TLS are the workhorses that provide the majority of security in the transmission of data over the Internet today. However, most people do not know that the degree of security and privacy inherent in a “secure” connection of this sort can vary from “almost none” to “really really good … good enough for US government TOP SECRET data”.  The piece which varies and thus provides the variable level of security is the “cipher” or “encryption technique”.  There are a large number of different ciphers — some are very fast and very insecure.  Some are slower and very secure.  Some weak ones (export-grade ciphers) are around from the days when the USA did not permit the export of decent security to other countries.

AES, the Advanced Encryption Standard, is a relatively new encryption technique/cipher that is the successor of DES.  AES was standardized in 2001 after a 5 year review, and is currently one of the most popular algorithms used in symmetric key cryptography (which, for example, is used for the actual data transmission in SSL and TLS).  It is also the “gold standard” encryption technique; many security-conscious organizations actually require that their employees use AES-256 (256-bit AES) for all communications.

This article discusses AES, its role in SSL, which web browsers and email programs support it, how you can make sure that you only use 256-bit AES encryption of all secure communications, and more.

Is SSL/TLS Really Broken by the BEAST attack? What is the Real Story? What Should I Do?

Wednesday, September 21st, 2011

Update – January, 2015.  SSL v3 should be turned off.  RC4 is now weak and should not be used anymore, even as a work around to the BEAST attack.  LuxSci recommends to use TLS v1.1+ and NIST-recommended ciphers.  The BEAST is not really considered a significant vector (even with TLS v1.0) compared to other things, anymore.

Update – April, 2012. openssl v1.0.1 is out and it supports TLS v1.1 and v1.2 which help mitigate this attack.  All web sites hosted by LuxSci now use this updated software and are safe from BEAST.  LuxSci recommends using a web host which supports TLS v1.1 and v1.2 for secure web connections.

SSL v3 and TLS v1 are subject to a serious exploit, according to a recently published attack mechanism (called BEAST).  This sounds foundation-shattering and kind of scary. When people see this, as when we did, the first panicky questions that arise are:

  • What is really affected?
  • How serious is it?
  • What can I do to protect myself?
  • How does the BEAST attack actually work?

After researching this issue, we have digested what we have found and produced this article to answer all of these questions for you.

LuxSci Gets a Fresh Look

Saturday, November 6th, 2010

LuxSci has finished updating its Web Interface, giving it a much more modern look via use of some technologies present in most modern web browsers, like Google Chrome, FireFox 3.6+, Safari, Opera 10, and Internet Explorer 9.

The web interface:

  • Now is now fully compatible with Internet Explorer 9 and Google Chrome for Mac
  • Is fastest in Google Chrome, out of all available web browsers
  • Looks best in: Google Chrome, FireFox 3.6+, or Safari 5
  • Still looks pretty good in Opera 10 and Internet Explorer 9
  • Looks fine in other supported browsers (the interface is backwards compatible with older technologies) like Internet Explorer 6-8, Opera 9, FireFox 2+, and older supported versions of Safari.

JAVA Applets Debut in LuxSci WebMail

Monday, January 26th, 2009

LuxSci has added plug-ins to its WebMail application in version 10.10 of LuxSci’s software which includes two JAVA applets.  So, were we hesitant to add JAVA applets, FLASH, ActiveX, and other plugins in the first place?  And why the sudden change of heart?  What does this mean for our customers who are concerned about security or who do not want or cannot use JAVA applets?
