Abstract (en)
[origin: FR2791202A1] The invention concerns a secure method for loading secret data from a first security module towards a second security module, said first module comprising secret data, said second module comprising a first non-volatile memory and a second volatile memory. The invention is characterised in that said method comprises steps which consist in: recording data comprising random data in the first memory of the second module; sending to the second module secret data from the first module encrypted from the random data; transferring the data comprising the random data from the first memory to the second memory of the second module; decrypting said encrypted secret data, from the random data; and recording, in the second memory, said decrypted secret data. The invention is particularly applicable to telephone systems.
