Packet RSA2048(Session_key + RSA1024(SHA256(Session_key))) Session_key + RSA1024(SHA256(Session_key)) RSA1024(SHA256(Session_key)) SHA256(Session_key)) Figure 1.1 RSA key exchange - Asymmetric vs symmetric Alternatives - Trade-off Security - complexity theory - purpose of the hash is not for security - Why does symmetric messages not need to be signed?
ZOC SSH Specific Features • Based on industry reference implementation OpenSSH • Client supports latest encryptions like ED25519 SHA256, SHA2 or AES-256ctr • SSH Public key, keyboard interactive or password authentication • Dynamic port forwarding (client as a SOCKS proxy) • X11 forwarding (lets you run X-Windows applications from the remote session) • Static port forwarding (tunneling of connections to remote destinations) • Proxy support (client connects to server through http/socks4/socks5) • SSH Agent forwarding between client and server • Client side SSH key generator • SFTP file transfer • SSH Keep-Alive http://www.emtec.com/ SSH Feature Details Key Exchange An especially difficult part of encrypted communication is the need to negotiate a shared secret (the key to use for encryption) over a public channel that could already be compromised.
Because the DecentraX masternodes are so powerful without incredible power usage, and feature programmable boards, users will be able to mine other SHA256-compliant coins while still participating in the DecentraX network.
