Title:
SECURE ACCESS METHOD AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/248088
Kind Code:
A1
Abstract:
Disclosed are a secure access method and an electronic device. The secure access method comprises: determining a target hardware module and a target buffer block according to a detection request; determining whether the target hardware module and the target buffer block belong to the same media path; when the target hardware module and the target buffer block belong to the same media path, determining whether the target hardware module has access rights to the target buffer block; and when the target hardware module has the access rights to the target buffer block, invoking the target hardware module to access the target buffer block. It can be seen that, by using the technical solution of the present application, an electronic device performs dual detection on a hardware module and a buffer block before the hardware module accesses the buffer block, such that the buffer block can be accessed securely, thereby avoiding the leakage of a secure media stream from a secure buffer block, and improving the security of an SMP.
