SSH Encryption Security Risks from Advanced Pattern Recognition Threats

Network security company SSH Communications said Friday that it is investigating claims that advanced pattern recognition can be used to weaken the security around an encryption standard used to protect connections between computers. The standard, known as secure shell, or SSH, encrypts the data traveling between an administrator's computer and a remote server, allowing for much more secure communications, even over the Internet.

That security, however, was called into question at a technical security conference last week, when three University of California-Berkeley researchers outlined a process by which guessing passwords sent using SSH can be made an estimated 50 times easier.

While the company acknowledged the research, SSH Communications called the problems highlighted by the paper "theoretical."
