Abstract: Systems and methods for the generation and use of session keys supporting secure communications between a client and server device are disclosed. The client device has or receives a password, which it hashes a predetermined first number of times. The hashed password is sent as a message digest to a server. The server applies the hashed password to an array of PUF devices, and receives a response bitstream which is stored. The client later hashes the password a second predetermined number of times, which is less than the first predetermined number, and this second message digest is sent to the server. The server continues to hash the second message digest, generate PUF responses, and compare the result to the initially stored responses. The number of hashes necessary to achieve a match is the session key.

Abstract: Systems and methods of improving public key infrastructure using PUF arrays are disclosed. The systems and methods are usable to improve PKI based on Lattice and Code cryptography. In the disclosed system, a client device includes an enrolled PUF array, and a server device acting as a Certification Authority includes an image of the PUF array including previously measured responses data for the devices in the PUF array. The CA sends a set of addresses to the client device, which generates a public key from measuring the response of PUF devices with the addresses. The CA receives the generated public key, and determines that the enrolled PUF was used to generate the key.

Abstract: An arrangement and method for detecting number splitting attacks in quantum key distribution systems is disclosed. According to the method, a receiver may detect the presence of an eavesdropper on a transmission channel by detecting an increase in the percent difference between the photon transmission rates of two signals of different wavelengths. The receiver may directly measure a percent difference in photon receive rates as between the two signals, and compare the measured difference with an expected difference. The expected difference may be known, or may be measured by the receiver on the basis of historical data. The expected difference may be computed from the percent difference between the means of the Poisson distributions of the transmitter's laser sources, which may be determined a priori and communicated to the transmitter.

Abstract: The present invention provides a method for using a tamper-resistant physical unclonable functions (PUF) to generate temporary passwords, encrypt a password manager database for one-way encryption, and authenticate users. Resistive Random-Access Memory (ReRAM) can be exploited as PUFs. On the server side, a ReRAM PUF can be used to change the format of the password manager database. By comparing the resistance values extracted from the ReRAM PUF, a bitstream can be generated which can then be used as a challenge. Furthermore, by utilizing the hash function and the ReRAM PUF, the password manager database's content can be encrypted as a one-way encryption. The resistance values, which are the ReRAM PUF output, are converted to a bitstream and then replace the user ID and password hash in the database.

Abstract: Lower-limb exoskeletons used to improve free-living mobility for individuals with neuromuscular impairment must be controlled to prescribe assistance that adapts to the diverse locomotor conditions encountered during daily life, including walking at different speeds and across varied terrain. This system employs an ankle exoskeleton control strategy that instantly and appropriately adjusts assistance to the changing biomechanical demand during variable walking. Specifically, this system utilizes a proportional joint-moment control strategy that prescribes assistance as a function of the instantaneous estimate of the ankle joint moment.

Abstract: A system and method of secure communication between computing devices based on physical unclonable functions such as memories having dissolvable conductive paths is provided. The method involves enrolling a client device, the client device having a PUF such as a pristine ReRAM. The PUF is enrolled in a secure environment by reading and storing the resistances of the PUF's addressable memory cells. The cells are categorized into “rugged” and “vulnerable” categories on the basis of their resistance, the vulnerable cells being those more likely to be permanently altered during the generations of PUF responses. The rugged cells are used for the generation of PUF responses for cryptographic key generation, but the vulnerable cells may be inspected to detect unauthorized 3rd party access to the PUF.

Abstract: A low-power, controllable, and reconfigurable method to control weights in model neurons in an Artificial Neural Network is disclosed. Memristors are utilized as adjustable synapses, where the memristor resistance reflects the synapse weight. The injection of extremely small electric currents (a few nanoamperes) in each cell forces the resistance to drop abruptly by several orders of magnitudes due to the formation of a conductive path between the two electrodes. These conductive paths dissolve as soon as the current injection stops, and the cells return to their initial state. A repeated injection of currents into the same cell results in an almost identical effect in resistance drop. Different, stable resistance values in each cell can be controllably achieved by injecting different current values.
