Secure Shell (SSH): Public Key Authentication over Hypertext Transfer Protocol (HTTP)

The Secure SHell (SSH) protocol requires all implementations to support public key authentication method (“Publickey”) for authentication purposes. HyperText Transfer Protocol (HTTP) applications which provide a SSH client over the web browser need to support “Publickey”. However, restrictions in HTTP, such as same origin policy, make it difficult to perform such authentications. In this paper, a system to perform “Publickey” authentication over HTTP is provided. It is ensured that no compromise is made that would pose a security risk to SSH protocol.
