HTTPS SSL encryption Vulnerable To Crypto Attack The secure sockets layer (SSL) and transport layer security (TLS) encryption protocol, used by millions of websites to secure Web communications via HTTPS, is vulnerable to being decrypted by attackers. Researchers have discovered a serious weakness in virtually all websites protected by the secure sockets layer protocol that allows attackers to silently decrypt data that's passing between a webserver and an end-user browser. Juliano Rizzo and Thai Duong say the vulnerability compromises TLS (Transport Layer Security) 1.0, the encryption mechanism that secures Web sites accessed using HTTPS (Secure Hypertext Transfer Protocol). TLS is the successor to SSL (Secure Sockets Layer) and is widely used at financial sites. Companies, including Google, Facebook, and Twitter, are urging the wider use of TLS on the Web. The exploit – demonstrated with a tool called BEAST – targets a flaw that could leave transactions open to attack a...
