Abstract: An application processor is provided. The application processor includes a cache coherent interconnect, a first master device connected to the cache coherent interconnect, a second master device, and a master-side filter connected between the cache coherent interconnect and the second master device. The master-side filter receives a snoop request from the first master device through the cache coherent interconnect, compares a second security attribute of the second master device with a first security attribute of the first master device which is included in the snoop request, and determines whether to transmit an address included in the snoop request to the second master device according to a comparison result.

Abstract: A data processing system includes an application processor, a memory device, and a channel connecting the application processor and the memory device. The application processor encrypts first data using a first encryption key and a first initialization vector in response to a write command, and transmits first encrypted data to the memory device through the channel. The memory device decrypts the first encrypted data using a second encryption key and a second initialization vector, and stores first decrypted data in a memory core. The second encryption key and the second initialization vector are stored in the memory device. The first encryption key is the same as the second encryption key, and the first initialization vector is the same as the second initialization vector.
