Enhanced Security: AES-256 Encryption for SSL and TLS

Tuesday, December 1st, 2020

AES-256 EncryptionSSL and TLS play critical roles in securing data transmission over the internet, and AES-256 is integral in their most secure configurations. The original standard was known as Secure Sockets Layer (SSL). Although it was replaced by Transport Layer Security (TLS), many in the industry still refer to TLS by its predecessor’s acronym. While TLS can be relied on for securing information at a high level—such as US Government TOP SECRET data—improper or outdated implementations of the standard may not provide much security at all.

Variations in which cipher is used in TLS impact how secure TLS ultimately is. Some ciphers are fast but insecure, while others are slower, require a greater amount of computational resources, and can provide a higher degree of security. Weaker ciphers—such as the early export-grade ciphers—still exist, but they should no longer be used.

The Advanced Encryption Standard (AES), is an encryption specification that succeeded the Data Encryption Standard (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. It is often seen as the gold standard symmetric-key encryption technique, with many security-conscious organizations requiring their employees to use AES-256 for all communications. It is also used prominently in TLS.

New “Mobile Mode” for PDAs and Smart Phones

Tuesday, September 8th, 2009

LuxSci has offered an “Xpress” WebMail portal for many years.  The portal is fast, simple, and works with most devices because it does not use any JavaScript or cookies, and uses few images.  The Xpress portal is good for security, privacy, and access from legacy devices, as well as over very slow connections.

However, the mobile device landscape is quickly changing.  Starting with the iPhone and its full-featured Safari web browser, to the Android, the Palm Pre, and the availability of browsers like OperaMini on many phones, it is now the case that many “cutting edge” phones actually have fast web browsers that fully support JavaScript, AJAX, CSS, and broadband — all the technologies formerly the purview of the desktop.  Their major drawback, however, is still the very small screen. Many of these browsers work perfectly well with most web sites, including LuxSci’s full-featured WebMail portal; however, it can be problematic and painful to use and navigate sites designed for large displays on these device’s small screens.

Enter LuxSci’s new “Mobile Mode”.  Mobile Mode is a new feature of LuxSci’s regular WebMail interface that is available when it detects that you are accessing it using a mobile device, such as an iPhone.
