  • Secure key agreement with untrusted parties
    Patent number: 11336442
    Abstract: Traditional key generation methods in a noisy network often assume trusted devices and are thus vulnerable to many attacks including covert channels. The present invention differs from previous key generation schemes in that it presents a mechanism which allows secure key generation with untrusted devices in a noisy network with a prescribed access structure.
    Type: Grant

  • Ultrafast quantum random number generation process and system therefore
    Patent number: 9218160
    Abstract: The invention is based on a process and system for producing random numbers by means of a quantum random number generator where the method comprises the steps of operating a laser in single mode and high modulation bandwidth by means of an electrical pulse driver, transforming the phase randomized optical pulses produced before in optical pulses with random amplitude and detecting the resulting random amplitude signals by means of a fast photodiode. The numbers thus produced are truly random.
