Abstract:
A processor, a method and a computer-readable storage medium for encrypting a return address are provided. The processor comprises hardware logic configured to encrypt an instruction pointer and push the encrypted instruction pointer onto a stack. The logic is further configured to retrieve the encrypted instruction pointer from the stack, decrypt the instruction pointer and redirect execution to the decrypted instruction pointer.
