Abstract: An object of the present disclosure is to provide a flight management apparatus capable of improving the safety of flying objects. In one example, a flight management apparatus (10) of the present disclosure includes a determination unit (12) configured to determine whether a specific space cell in a space is already reserved based on a reservation state about the specific space cell, when the flight management apparatus receives a request for permission to move to the specific space cell from a flying object; and a permission unit (13) configured to permit the movement to the specific space cell of the flying object when the determination unit determines the specific space cell is not reserved, and not to permit the movement to the specific space cell of the flying object when the determination unit determines the specific space cell is already reserved.

Abstract: A limited memory system uses statically linked code from different entities, with each entity having a fixed code space. Entry points for each code space are located at a fixed external address and referenced to a jump address inside each code space. Dummy code containing relevant entry point addresses is used to simulate the code of other entities for compilation and linking. Each entity is able to update its own code without the need for source code from the other entities that would typically be required in traditional statically-linked code.

Abstract: A method at a terminal in a multiple-node digital communications network, comprising any one or more of: generating at least one symmetric first key(s), across all participating nodes in the multiple-node digital communications network and securely distributing the at least one first key(s) in encrypted form to multiple participating nodes of the multiple-node digital communications network, using at least one asymmetrically established second key(s), the participating nodes including at least one message-transmitting node(s) and at least one message-receiving node(s); generating at least one symmetric third key(s) for one or more communication session that includes one or more communications from the at least one message-transmitting node(s) to the message-receiving node(s); encrypting at least one payload message using the at least one third key(s) at the at least one message-transmitting node(s), sending the encrypted at least one payload message, and receiving the encrypted at least one payload message at
