发明名称 Method for secure software upgrade in a security module
摘要 <p>The method involves forming an updating program block (PBI) and determining a target memory zone of a safety mobile. Pre-stored contents in the target zone are determined, and the pre-stored contents and the program block are combined to form a program code (SBI). The program code is transmitted to the mobile and the target memory of the updating block is obtained by inverse mixing of the contents and the block.</p>
