WebThe Clipper Chip was a cryptographic chipset developed and promoted by the US Government. It was intended for implementation in secure voice equipment, such as crypto phones, and required its users to surrender … WebThe Clipper chip would not decode messages with an invalid hash; however, the 16 bit hash was too short to provide meaningful security. A brute force attack would quickly produce another LEAF value that would give the same hash but not yield the correct keys after the escrow attempt. This would allow the Clipper chip to be used as an encryption ...
