Abstract
The present application discloses a processor and an attack detection method thereof. The processor includes a first register and an execution unit. The execution unit is configured to: execute a first jump-related instruction under a first privilege mode; set a first field of the first register to a first jump status parameter according to execution of the first jump-related instruction; jump to a first corresponding instruction in a specified register of the first jump-related instruction; determine whether the first corresponding instruction is a legal instruction and whether a first parameter of the first corresponding instruction is equal to the first jump status parameter to obtain a first determination; and determine whether to send an alert message according to the first determination.
