Abstract
A method for accelerating sleep startup speed is provided. The method may include determining that a system-on-chip (SoC) is under a sleep mode; determining that a wake-up condition is met; calculating a second authentication key based on data stored in a flash memory of the SoC using a cryptographic algorithm; comparing the second authentication key with a first authentication key, wherein the first authentication key is associated with a secure boot of the SoC and obtained from an Always On (AON) memory of the SoC; and in response to a comparison result that the first authentication key is the same as the second authentication key, waking the SoC up from the sleep mode.
