Abstract
The invention relates in particular to a method for carrying out an electronic draw in a device, the device comprising a first and second part, the first part being secure. After having obtained (505, 530), in the first part, at least one raw random number and at least one signature private key, said private key having been stored beforehand in the first part, said at least one obtained raw random number is signed, in the first part, using said at least one obtained private key, and transmitted (540) to a drawing module implemented in the second part.

Method for carrying out an electronic draw in a device, the device comprising a first and second part, the first part being secure, the method comprising,
- obtaining in the first part, at least one raw random number,
- obtaining in the first part, at least one signature private key, said at least one signature private key having been stored beforehand in the first part,
- signing in the first part, said at least one raw random number obtained using said at least one signature private key obtained to obtain signed data, and
- transmitting the signed data to a drawing module implemented in the second part.
A system to perform an electronic draw comprising a first and second device, the first device being secure and comprising a data processing unit configured to:
- obtain at least one raw random number,
- obtain at least one signature private key,
- sign said at least one obtained raw random number obtained using said at least one signature private key obtained to obtain signed data, and
- transmit the signed data to a drawing module implemented in the second device.
