Abstract:
A system for creating a secure wireless channel between a laptop computer and a video projector. The system allows a person, or presenter, to send presentation information wirelessly without having to worry about unwanted eavesdroppers receiving the presentation information. Prior to the presentation, the projector generates a random number and projects the number on a screen. The presenter types the random number into his computer and an encryption program within the computer uses the random number to create a temporary session key. Advantageously, the random number is never transmitted wirelessly. The session key is then used to encrypt the presentation information before the information is wirelessly transmitted to the projector. The projector receives the information and uses the same random number to decrypt the presentation information. After decryption, the presentation information is projected on a screen for presentation to the audience.
