Which one of the following feature was present in SSH protocol, versio...
Explanation:
In the SSH (Secure Shell) protocol, version 1, none of the mentioned features were present. Let's explore the options to understand why they were not available in SSH protocol version 1.
a) Password changing:
In SSH protocol version 1, there was no support for changing passwords. The user had to rely on the existing password provided during the authentication process. Password changing functionality is not a part of the SSH protocol itself but can be implemented at the system level.
b) Periodic replacement of session keys:
SSH protocol version 1 did not include support for periodic replacement of session keys. Session keys are established during the SSH connection setup and are used for encryption and integrity protection of the communication between the client and server. The periodic replacement of session keys is a security measure to mitigate the impact of potential key compromises. However, in SSH protocol version 1, this feature was not implemented.
c) Support for public-key certificates:
SSH protocol version 1 did not support public-key certificates. Public-key certificates are used to bind public keys to identities, providing a means of authentication and establishing trust. While SSH protocol version 1 did support public key authentication, it did not have the concept of certificates.
Therefore, the correct answer is option 'D' - none of the mentioned. None of the mentioned features were present in SSH protocol version 1. It's important to note that SSH protocol version 1 had several security vulnerabilities and limitations, leading to the development of SSH protocol version 2, which addressed these issues and introduced many new features and improvements.
