  • Patent number: 11943340
    Abstract: In some examples, for process-to-process communication, such as in function linking, a virtual channel can be provisioned to provide virtual machine to virtual machine communications. In response to a transmit request from a source virtual machine, the virtual channel can cause a data copy from a source buffer associated with the source virtual machine without decryption or encryption. The virtual channel provisions a key identifier for the copied data. The destination virtual machine can receive an indication data is available and can cause the data to be decrypted using a key accessed using the key identifier and source address of the copied data. In addition, the data can be encrypted using a second, different key for storage in a destination buffer associated with the destination virtual machine. In some examples, the key identifier and source address is managed by the virtual channel and is not visible to virtual machine or hypervisor.

  • Publication number: 20220234074
    Abstract: The present invention discloses a manufacturing method of color filter. The method comprises the following steps. First, the method deposes a first color material on the substrate via a first pattern mask, forming a first color pattern, and a spray coating method is used for spraying a first color material on the substrate via the first pattern mask, therefore to form a first color pattern. Thereafter, the first pattern mask is removed and cleaned a first residual material of the first color material via laser or blow gun. The abovementioned steps will be repeated for three times to finish the color filter.
