Internet webcam signals from webcams could emerge as an exotic but effective new tool for securing terrestrial communications against eavesdropping.
Scientists have come up with a method for encrypting messages using the internet objects, which emit signals and are thought to be powered by DC voltage. Scientists at the National Institute of Cool Security Ideas (NICSI) propose using the signals emitted by webcams to lock and unlock digital communications in a secure fashion. The researchers believe webcams could make an ideal cryptographic tool because the signals they emit are impossible to predict. "Webcam-based cryptography is based on a physical fact that such a webcam signal is random and has a very broad frequency spectrum." NICSI scientists suggest using an agreed webcam signal to add randomness to a stream cipher. Each communicating party would only need to know which webcam to monitor and when to start in order to encrypt and decrypt a message. Without knowing the target webcam and time an eavesdropper should be unable to decrypt the message. NICSI scientists believes voyeur-cryptography could appeal to anyone who requires high-security communications. He adds that the method does not require a large radio antenna like quasar encryption because the signals exist already on the internet. Plus quasar signals are really boring compared to many webcam signals. --------------------------------------------------------------------- The Cryptography Mailing List Unsubscribe by sending "unsubscribe cryptography" to [EMAIL PROTECTED]
