Secure Shell (SSH) is a protocol allowing secure remote login to a computer on a network using public-key cryptography.SSH client programs (such as ssh from OpenSSH) typically run for the duration of a remote login session and are configured to look for the user's private key in a file in the user's home directory (e.g., .ssh/id_rsa).
Formally, a message authentication code (MAC) system is a triple of efficient [4] algorithms (G, S, V) satisfying: G (key-generator) gives the key k on input 1 n, where n is the security parameter. S (signing) outputs a tag t on the key k and the input string x. V (verifying) outputs accepted or rejected on inputs: the key k, the string x and ...

In cryptography, an HMAC (sometimes expanded as either keyed-hash message authentication code or hash-based message authentication code) is a specific type of message authentication code (MAC) involving a cryptographic hash function and a secret cryptographic key. As with any MAC, it may be used to simultaneously verify both the data integrity ...
Key /Config-authentication is used to solve the problem of authenticating the keys of a person (say "person A") that some other person ("person B") is talking to or trying to talk to. In other words, it is the process of assuring that the key of "person A", held by "person B", does in fact belong to "person A" and vice versa.
Mutual authentication is a crucial security step that can defend against many adversarial attacks, [3] which otherwise can have large consequences if IoT systems (such as e-Healthcare servers) are hacked. In scheme analyses done of past works, a lack of mutual authentication had been considered a weakness in data transmission schemes. [4]
This means that the SSH server will only be aware of the IP address of the web application server, keeping the actual client's IP address hidden. Auditability: Because all communication between the client and the SSH server must pass through the web application server this communication can be logged. This prevents a malicious client from ...
Public key authentication (usually implemented with a HTTPS / SSL client certificate) using a client certificate. Kerberos or SPNEGO authentication, employed for example by Microsoft IIS running configured for Integrated Windows Authentication (IWA). Secure Remote Password protocol (preferably within the HTTPS / TLS layer). However, this is not ...
