The RC4 Stream Cipher could be the most common stream cipher used on the Internet. RC4 is the only Stream Cipher which is standardized for the SSL/TLS protocol, it is also used for WEP and WPA protected wireless networks. Initially, RC4 was designed to be a closed source commercial product, with the core algorithm kept secret. In 1994, the source code for RC4 was posted on the internet and the algorithm could be analyzed.

The first attack on RC4 was published by Fluhrer, Mantin, and Shamir in 2001. The attack is very effective, but can only be used against certain keys starting with a special …

As a general attack against encryption software on a computer, the cold boot attack was presented at 25C3. To encrypt data on a PC, many programs store the encryption key in RAM. The key is usually derived from a password or loaded from the hard disk where it is protected by a password too. The key resists as least as long as the encryption operation take in RAM. For many applications like Full-Disk-Encryption or Email Signatures, it is convenient to keep the key permanently in RAM, once it has been loaded, so that the user doesn’t need to enter his password again and again.

To protect the key …

SSL/TLS is the standard when it comes to securing HTTP traffic on the internet. The authenticity of a web server is usually secured using a X.509 certificate digitally signed by a trusted certification authority (CA). All major web browsers come with a list of CAs preinstalled they assume as trustworthy. Every website can be signed by any of these CAs, so no web browser would show a warning, if www.dod.gov would be signed by a Chinese certification authority or the Deutsche Telekom.

To examine the usage of X.509 certificates for SSL/TLS, the EFF installed a SSL Observatory:
