Experts Uncover Passive Method to Extract Private RSA Keys from SSH Connections

According to a recent study, passive network attackers can potentially obtain private RSA host keys from a susceptible SSH server by timing naturally occurring computational errors that arise during the connection establishment process.

Over an unprotected network, commands can be safely transmitted and computer logins can be accomplished with the help of the Secure Shell (SSH) protocol. SSH, which has a client-server architecture, encrypts and verifies device connections using cryptography.

In the SSH protocol, a cryptographic key called a host key is used to authenticate computers. Key pairs known as “host keys” are usually produced by public-key cryptosystems read more Experts Uncover Passive Method to Extract Private RSA Keys from SSH Connections.
