The invention relates to the technical field of embedded software radio, in particular to a remote procedure call (RPC) system and method based on MHAL / MOCB. The SCA platform software architecture is used for an SCA platform software architecture core framework comprising a server side and a client side; and the core framework client establishes connection with the core framework server by means of the RPC middleware based on the MHAL / MOCB remote procedure call. The server and the client among the nodes are communicated on the SRIO bus by adopting a protocol based on a hardware abstraction layer (MHAL / MOCB), and the communication speed is higher than that of the traditional Ethernet based on TCP / IP (Transmission Control Protocol / Internet Protocol).

The embodiment of the invention discloses a loop bus communication method and device, electronic equipment and a storage medium, and relates to the technical field of industrial automation and intelligent control, and the method comprises the steps: carrying out the initialization of Master and Slave equipment through setting a current pulse signal threshold value, a return code data representation mode and a high-low voltage pulse width standard; the Master equipment sends downlink data by modifying a low-voltage pulse duty ratio and indicates a return code state by using a high-level pulse duty ratio, and the Slave equipment realizes full-duplex communication by changing a bus current return code. For address conflicts possibly caused by simultaneous code returning of multiple Slave devices, the Master device automatically triggers an address redistribution process by detecting the size of code returning current and a sequential relationship. A low-power-consumption timer is used for controlling the Slave device to be awakened only when a communication request is requested, and the Master device dynamically adjusts transmission parameters and speed by monitoring bus signal quality. According to the invention, the problems of low transmission efficiency and incapability of real-time arbitration and address conflict detection in the prior art are effectively solved.

The application discloses a non-balance privacy set union method and a union set system based on full homomorphic encryption, and the method comprises the following steps: a sending end sends a first to-be-unionized ciphertext set to a receiving end; the receiving end obtains a comparison result ciphertext by comparing the data difference between a first to-be-unionized set and a second to-be-unionized set according to the first to-be-unionized ciphertext set based on assignment, rotation and multiplication operation, and sends the comparison result ciphertext to the sending end; the sending end decrypts the comparison result ciphertext to obtain a blinded comparison result, and sends the blinded comparison result to the receiving end; and the receiving end determines the union set of the first to-be-unionized set and the second to-be-unionized set according to the blinded comparison result. The application can reduce the calculation amount and improve the communication speed while avoiding privacy leakage.
