In a method for gathering time-variable data from electronic slave devices in data communication through a data transmission channel with an electronic master device, the slave devices periodically measure and store a current value of at least one respective time-variable parameter (P(t), . . . Pn(t)). The master device sends a freeze command to the slave devices. Upon receipt of the freeze command from the master device, the slave devices freeze the last measured value of the at least one time-variable parameter. During a data-gathering time interval following sending of the freeze command, the master device gathers the frozen values from the slave devices.

A method for transmitting a file from a file source () to a plurality of electronic devices () is described herein. To each electronic device are associated an encryption key and a unique identifier code. According to the method described herein, to the plurality of electronic devices are transmitted: a file encrypted by means of a session key, and a plurality of encrypted session keys, each paired with a respective electronic device, with whose encryption key the respective encrypted session key was obtained; Moreover, each electronic device decrypts its own encrypted session key using the respective encryption key to obtain the decrypted session key, and decrypts the encrypted file by means of the decrypted session key.

Method and system for transferring firmware or software to a plurality of devices

To protect a software to be transferred to programmable electronic devices, a management system for programmable electronic devices is provided, comprising: a plurality of electronic devices (), each identified by at least one unique identification parameter (ID) and containing at least one encryption key (Key); &#x2014;at least one protected site () in which a protected database () resides, in which the unique identification parameter (ID) and the encryption key (Key) are stored for each electronic device (); &#x2014;a server () programmed to receive a request for transmission of a software from a device () and to generate an encrypted version of said software, using the encryption key (Key) associated in the database () with the unique identification parameter (ID) of the device () that has requested the transmission of said software.

Method and system for protected transmission of files

A method is described for the transmission of data among devices (D, D, . . . D, . . . D) connected to a communication channel (1) through sequences containing at least two symbols, one dominant ('0') and one recessive ('1'). According to this transmission method, one (D) of the devices connected to the communication channel (1) has the function of time slot generator and it transmits on the communication channel (1) with a transmission frequency (f) a sequence of symbols, each defining a time slot in a sequence of time slots. The sequence of symbols comprises at least a series of recessive symbols (&#x201c;1&#x201d;). When one of the devices (D) has to transmit on the communication channel (1), it generates a sequence of symbols, synchronized with the sequence of time slots generated by the time slot generator device (D) and comprising at least one dominant symbol (&#x201c;0&#x201d;).
