Controlling access between nodes by a key server

A computer system for facilitating processing in a computing environment, the computer system comprising:

• a memory;
• and
• a processor in communication with the memory, wherein the computer system is configured to perform a method, the method comprising:
• controlling, by a key server, access between a plurality of nodes of the computing environment, the controlling access including:
• receiving, by the key server from one node of the plurality of nodes, a request for a shared key, the shared key created for a selected node pair;
• determining, by the key server, whether the one node is a node of the selected node pair, wherein the determining checks an alternate name of the one node to determine whether it matches an alternate name associated with the shared key;
• and
• providing, by the key server, the shared key to the one node, based on determining the one node is a node of the selected node pair.

A computer-implemented method of facilitating processing in a computing environment, the computer-implemented method comprising:

• controlling, by a key server, access between a plurality of nodes of the computing environment, the controlling access including:
• receiving, by the key server from one node of the plurality of nodes, a request for a shared key, the shared key created for a selected node pair;
• determining, by the key server, whether the one node is a node of the selected node pair, wherein the determining checks an alternate name of the one node to determine whether it matches an alternate name associated with the shared key;
• and
• providing, by the key server, the shared key to the one node, based on determining the one node is a node of the selected node pair.
