Information related to noise sampled from the control module is obtained. A first encryption key is calculated based on the information. Firmware to be updated on the control module is received from a host of the modular assembly system. The firmware is encrypted based on at least a second encryption key. In response to determining that the received firmware can be decrypted, the decrypted firmware is loaded into the control module. At least one of the obtaining, calculating, receiving, determining, and loading is performed by the control module. ## Claims ### Claim 1 A method for updating firmware on a control module of a modular assembly system, the method comprising: obtaining information related to noise sampled from the control module; calculating a first encryption key based on the information; receiving, from a host of the modular assembly system, firmware to be updated on the control module, the firmware encrypted based on at least a second encryption key; determining that the received firmware can be decrypted based on the first encryption key; and in response to determining that the received firmware can be decrypted, loading the decrypted firmware into the control module, wherein at least one of the obtaining, calculating, receiving, determining, and loading is performed by the control module. ### Claim 2 (depends on 1) The method of claim 1, further comprising: storing the first encryption key in a persistent storage of the control module. ### Claim 3 (depends on 2) The method of claim 2, further comprising: in response to receiving the firmware to be updated, retrieving the first encryption key from the persistent storage. ### Claim 4 (depends on 1) The method of claim 1, further comprising: receiving, from the host, a message for requesting firmware update; and in response to receiving the message, transmitting, to the host, the first encryption key. ### Claim 5 (depends on 1) The method of claim 1, wherein the received firmware can be decrypted based on the first encryption key when the first and second encryption keys are the same. ### Claim 6 (depends on 1) The method of claim 1, wherein the noise is sampled from power supply of the control module. ### Claim 7 (depends on 1) The method of claim 1, wherein the obtaining further comprises: sampling the control module to obtain an initial signal; filtering the initial signal to obtain an filtered signal; and computing a noise signal based on at least the initial signal and the filtered signal. ### Claim 8 (depends on 7) The method of claim 7, wherein the sampling is performed by analog-to-digital conversion (ADC); the filtering is performed by Kalman filtering; and the computing is performed by a subtraction operation. ### Claim 9 (depends on 1) The method of claim 1, wherein the firmware to be updated on the control module is divided into a plurality of packages that are sequentially transmitted to the control module. ### Claim 10 (depends on 9) The method of claim 9, wherein a size of each of the plurality of packages is the same. ### Claim 11 A method for encrypting firmware to be updated on a control module of a modular assembly system, the method comprising: receiving, from the control module, an encryption key calculated based on information related to noise sampled from the control module; encrypting firmware based on at least the encryption key; and transmitting, to the control module, the encrypted firmware, wherein at least one of the receiving, encrypting, and transmitting is performed by a host of the modular assembly system. ### Claim 12 (depends on 11) The method of claim 11, further comprising: transmitting, to the control module, a message for requesting firmware update. ### Claim 13 (depends on 11) The method of claim 11, wherein the transmitting further comprises: dividing the firmware into a plurality of packages; and sequentially transmitting, to the control module, each of the plurality of packages. ### Claim 14 (depends on 13) The method of claim 13, wherein a size of each of the plurality of packages is the same. ### Claim 15 (depends on 11) The method of claim 11, wherein the noise is sampled from power supply of the control module.
