Abstract: There is provided a method for secure communications. The method includes a computing device receiving a notification comprising a message, a counter value, a signature signed by a signer and based on the message and the counter value, and an indication of the signer. The device obtains a current counter value based on an identity of the signer, checks the signature and compares the counter value with the current counter value; and, if the counter comparison and the signature checking is successful, accepting the message.

Abstract: Challenge-response authentication protocols are disclosed herein, including systems and methods for a first device to authenticate a second device. In one embodiment, the following operations are performed by the first device: (a) sending to the second device: (i) a challenge value corresponding to an expected response value known by the first device, and (ii) a hiding value; (b) receiving from the second device a masked response value; (c) obtaining an expected masked response value from the expected response value and the hiding value; and (d) determining whether the expected masked response value matches the masked response value received from the second device. The operations from the perspective of the second device are also disclosed, which in some embodiments include computing the masked response value using the challenge value, the hiding value, and secret information known to the second device.

Abstract: A method for operating a pseudorandom generator is disclosed. The method may be implemented by a processor of a mobile computing device. The method includes: collecting raw sensor data from at least one sensor associated with the mobile computing device; selecting a subset of the raw sensor data; retrieving first representation representing accumulated entropy associated with one or more previously acquired raw sensor data sets for the at least one sensor; and generating a seed for a pseudorandom generator based on combining the first representation and the selected subset of raw sensor data.

Abstract: A method of processing a notification that is broadcast by a source server is disclosed. The method includes: receiving, at the computing device, the notification, the notification containing a first message; storing the first message in a message store; determining that the first message is a repeated message of a previous message that was received at the computing device prior to receiving the notification; and associating a message counter value of the first message with the previous message and a message counter value associated with the previous message in the message store.

Abstract: In some aspects of what is described here, a first wireless device detects proximity of a second wireless device (e.g., by a Near Field Communication (NFC) interface or another type of interface). Based on detecting proximity of the second wireless device, the first wireless device generates a recommendation request from information received from the second wireless device. The first wireless device sends the recommendation request to a trusted authority and receives a response. The response includes the trusted authority's recommendation whether to trust the second wireless device. The first wireless device can determine whether to trust the second wireless device based on the recommendation.
