Secure communication with an end device through an intermediary system
An example intermediary system allows an owner computer system to securely identify and communicate with an end device. The end device uses master secret and time data shared with the owner computer system to generate and advertise a time-dependent device identifier and potentially an encrypted device message. The intermediary system augments the received device data with a message (e.g., an estimate of the device's location) encrypted using the time-dependent device identifier as an encryption key. Furthermore, it hashes the time-dependent device identifier for additional security. The augmented data is forwarded to a server for retrieval and processing by the owner computer system. The owner uses the shared master secret, time data and hash function to generate a hashed time-dependent device identifier used to retrieve matching augmented data from the server. The retrieved message data is decrypted using the reverse of the encryption operations. |

Receiver-transmitter impedance co-matching method using bondwires
Semiconductor chips are made increasingly smaller, thanks to improved design techniques and process scaling. Sometimes the bottleneck is not the chip itself but the package size due to many necessary pins.

Therefore, single-ended RF input/output is used for transceiver, and the same pin is shared between RX and TX. A receiver (RX)-transmitter (TX) impedance co-matching method uses multiple bondwires for transceivers sharing one input/output (I/O) pin between RX and TX. The RX input impedance and TX output impedance are transformed closer to each other or even to the same impedance, which makes it possible to get the best RX and TX performance with just one matching network. The chip area is also saved without using on-chip inductors. |
