1. A processing method for defending against shared storage side channel attacks, comprising:
receiving, by a clock thread, a first request to acquire time information from an attack thread, the clock thread comprising a thread that processes timing programs, the attack thread comprising a thread that performs side channel attacks;
acquiring first time information by the clock thread, the first time information comprising a time point when the first request is received;
obfuscating the first time information to obtain second time information; and
transmitting, by the clock thread, the second time information to the attack thread, so that the attack thread performs side channel attacks based on the second time information.
