Abstract: A method, system, computer readable media and cloud systems are provided for generating views of a virtual reality environment for a spectator. One example method includes enabling a spectator to view into a virtual reality environment, and control what specific content within the environment the spectator wishes to see. Motions of an HMD worn by an HMD player can be tracked so as to provide a geared spectator view into the virtual reality environment. The gearing of the spectator view enables a spectator to view the virtual reality content in a more normal way which is not tied to the strict movements of the HMD worn by the HMD player. The gearing effects can be programmable or can be set based on the content being navigated by the HMD player or preferences of the individual spectators.

Abstract: Aspects of the invention include channel key loading of a host bus adapter (HBA) based on a secure key exchange (SKE) authentication response by a responder node of a computing environment. A non-limiting example computer-implemented method includes receiving an authentication response message at an initiator channel on an initiator node from a responder channel on a responder node to establish a secure communication, the receiving at a local key manager (LKM) executing on the initiator node. A state check is performed based on a security association of the initiator node and the responder node. A validation of the authentication response message is performed. An identifier of a selected encryption algorithm is extracted from the authentication response message. The initiator channel requests to communicate with the responder channel based at least in part on a successful state check, a successful validation, and the selected encryption algorithm.

The rekey timer is one of a shared key rekey timer for a current shared key between the first node and a second node, and a session key rekey timer for a session key used in a secure communication between a channel on the first node and a channel on the second node.

Based on the rekey timer being the shared key rekey timer, a new shared key is obtained and stored as the current shared key. Based on the rekey timer being the session key rekey timer, a new session key that is based at least in part on the current shared key is obtained and used in the secure communication.
