Described herein are systems and methods that allow for secure wireless communication between a contact lens system and an accessory device to protect sensitive data and prevent unauthorized access to confidential information. In certain embodiments, tampering attempts by potential attackers are thwarted by using a Physically Unclonable Functions (PUF) circuit that is immune to reverse engineering. In addition, sensors monitor a to-be-protected electronic device to detect tampering attempts and physical attacks to ensure the physical integrity of the communication system.

Secure communication between a contact lens and an accessory device

A method, implemented in a communication device, of indicating a service supported by the communication device. A hash value is generated, using a hash function, based on a service identifier associated with the service. Respective portions of the hash value are mapped to respective bit locations in a bit string that represents membership of the service in a set of services supported by the communication device. The bit string is generated at least by setting the bit locations in the bit string to values that indicate that the service is supported by the communication device.

The present disclosure describes apparatuses and techniques for secure device authentication. In some aspects, a public ephemeral key of a device is exposed. A message received from a remote device to authenticate includes a hash of the public ephemeral key of the device, a public ephemeral key and an encrypted public key of the remote device, and an encrypted hash value useful to prove ownership of the public key received from the remote device. An encryption key is generated based on the public ephemeral key of the remote device and a private ephemeral key of the device. The device then decrypts, with the encryption key, the encrypted public key of the remote device and the encrypted hash value. The remote device is then authenticated by verifying, based on the decrypted hash value, that the remote device owns the decrypted public key.

Methods and apparatus for secure device authentication

In a method for efficient password based public key authentication between a first user device and a second user device, a shared password is received by a first user device which generates a first hash value of the shared password and a first value, wherein the first value is composed of at least a product of the first hash value and a first unique security constant associated with the first user. The first user device then generates a first random value generated using data from a generator element, and a first blind public key associated with the first user device, wherein the first blind public key is generated using a first public key. The first user device concurrently sends the first value and the first blind public key to the second user device for authentication.

The present disclosure describes apparatuses and techniques for measuring position and velocity. In some aspects, Global Navigation Satellite System (GNSS) signals and feedback information are received. The feedback information may include predicted code phase information and predicted Doppler information. The feedback information is used to define a LOS region of a search space, the search space having dimensions in a code phase domain and in a Doppler domain. The GNSS signals within the search space are operated on to produce measurements of the GNSS signals across the code phase domain and the Doppler domain of the search space. The produced measurements are operated on within the LOS region of the search space to select measurements associated with a line of sight (LOS) signal. The selected measurements are operated on to produce position and/or velocity information associated with the LOS signal.

The present disclosure describes techniques and apparatuses for device-to-device radio frequency proximity determination. These techniques, in contrast to conventional cellular and GPS services, can accurately locate mobile devices at relatively low cost. In some aspects, three or more mobile communication devices communicate radio frequency ranging signals and, using information about these signals, a distance and direction between two of the devices is determined. In some other aspects, two mobile communication devices communicate radio frequency ranging signals separated in time, and after movement of one of the mobile communication devices. Using information about these two signals, a distance and direction between the two devices is determined.
