A group of cryptographers has developed a new attack that has broken Kasumi, the encryption algorithm used to secure traffic on 3G GSM wireless networks. The technique enables them to recover a full key by using a tactic known as a related-key attack, but experts say it is not the end of the world for [...]

Quote from Bruce Schneiers page :
This presentation will show the first experimental implementation of an eavesdropper for quantum cryptosystem. Although quantum cryptography has been proven unconditionally secure, by exploiting physical imperfections (detector vulnerability) we have successfully built an intercept-resend attack and demonstrated eavesdropping under realistic conditions on an installed quantum key distribution line. The actual [...]

Tool name :
RC4Encryption 0.1
Description :
RC4Encryption is a tool to encrypt and decrypt files with the RC4 algorithm. The tool itself is not really hot stuff. OpenSSL supports RC4 since years and also many other algorithms. But you can use this code without any dependency of an additional library and you have working functions of stream [...]
