METHOD FOR SECURED CRYPTOGRAPHIC DATA TRANSMISSION

摘要

The invention relates to a method for the secure transmission of data between two computer devices, a first device comprising means for transmitting an analog signal and a second device comprising means for acquiring the analog signal, the method comprising steps, implemented by the first device, of: generation of a first analog signal representative of a first cryptographic data item comprising an encryption key, transmission of the first analog signal via the transmission means included in the first device, intended for means of acquisition included in the second device, reception of second cryptographic data from the second device, said second data being at least partly encrypted using the encryption key, processing of said second cryptographic data as a function of the first cryptographic data item, comprising a decryption of said data second data.
