<p>PURPOSE: A system, a device, and a method for the collaborative execution of a software application decode the super code of a first encoding command and obtain the first encoding command. CONSTITUTION: A first encoding command is obtained (S10). A session key is encoded by using an encoding symmetric encoding algorithm and a first key (S11). A first coded command and the coded session key are transmitted to a second device (S12). A second coded command is received from the second device (S16). A non-coded command is obtained by decoding a second encoding command by using the symmetric encoding algorithm and the session key. The non-coded command is executed (S18). [Reference numerals] (110) Host; (120) Circuit; (S10) Decode J, a pre-encoded command; (S11) Obtain L by decoding J and a padding K_2 by using a key K_1; (S13) Obtain J and I by decoding L by using K_1; (S14) Obtain I by decoding J; (S15) Encode I by M=K_2; (S17) Obtain I by decoding M by using K_2; (S18) Execute I</p> |
