The method is used in a processor in the isolated execution environment of a system-on-a-chip. The method includes: accessing an output command of a main system processor in a main system of the system-on-a-chip; reading first data from a shared memory in the main system according to the output command; encrypting the first data with a private key and generating encrypted first data; and outputting the encrypted first data to the external memory."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and system for protecting data in external memory based on isolated execution environment","description":"A method for protecting data in an external memory based on an isolated execution environment is provided.
