Secure Wireless Protocol

Project goal: To create a system of wireless transceivers that communicate with a fast, consistent stream to transmit acceptable quality audio. The designed system consists of a microphone, computer and two speakers,each with its own wireless transceiver. The transmission is secured by use of an Advanced Encryption Standard protocol compatible with the transceivers. The intended system application is simplification of a dispatch center setup by reducing the wiring used for audio equipment. With this system’s integrated encryption, sensitive information can be transmitted securely. To secure the transmission the design requires insertion of a physical encryption key to begin transmission. Using a physical rather than digital key eliminates wireless exchange of keys, reducing the likelihood of any transmission being compromised. Off-the-shelf components were modified to fit the requirements of the design. Testing of the system verified data transmission speeds and encryption methods. Additional testing quantified wireless transmission range and audio quality.
