  • Patent number: 11750580
    Abstract: A system, computer-readable storage medium, and method for secure network communication. A first device employs a first secret to establish a stream between the first and a second device. A third key, first ciphertext based on a first key, and hash of the first key are received from the second device by the first. A second key is applied to recover a second secret from the first ciphertext. The third key is encrypted to generate a second ciphertext including a third secret. Fourth and fifth keys are derived based on the first, second, and third secrets. A message authentication code is generated based on the fourth and third keys, first ciphertext, hash of the first key, and second ciphertext. The second ciphertext and message authentication code are transmitted by the first to the second device, and the fifth key is employed by the first device to modify the stream.

  • Patent number: 8698634
    Abstract: An integrated monitoring and multichannel communication system for the management of rescue teams, especially those fighting forest fires, comprises a suit, worn by a rescue worker; an electronic system; a telecommunication system; and an information system. The suit integrates fireproof, waterproof, heatproof and impact resistant materials to integrate, protect and allow access to the electronic system. The electronic system collects biometric and location data from the rescue worker, transmitting said data to a panel located in the back of the suit. The telecommunications system sends the biometric, orientation and location data, in real-time through an Ultra High Frequency network, to a computer integrated into a support vehicle, which in its turn sends the data to a server. The information system collects and manages the data to monitor the biometric, orientation and location data, to receive critical alerts and through maps to define deployment strategies for the rescue worker.

  • Publication number: 20090313748
    Abstract: The present invention consists of an integrated monitoring and multichannel communication system for the management of rescue teams, especially those fighting forest fires, comprising a suit (1), worn by all operational suited units in the terrain; and electronic system (2); a telecommunication system (4) and an information system (3). The suit integrates fireproof, waterproof, heatproof and impact resistant materials, which as a unit integrate, protect and ease access to the electronic system. The electronic system (2) collects biometric and location data from the operational suited units in the terrain, transmitting said data to a panel located in the back of the suit. The telecommunications system (4) sends the biometric, orientation and location data, in real-time through an Ultra High Frequency network, to a computer integrated into a support vehicle, which in its turn sends the data, via terrestrial or satellite communications, to a server.
