One possible method was to create a LEAF with another key, that was different to the used session key. This LEAF would be considered to be valid by the counterpart.
	As the LEAF was only validated by the 16 Bit checksum, it was also possible to just create a random string as LEAF. It would take in average 2^16 tries to generate a valid LEAF with this method.

	These vulnerabilities and the growing public backlash regarding the key escrowing and privacy concerns lead to the failure of the Clipper Chip. Companys were not willing to use the Clipper Chip for their products and people were not willing to use it. Only one product was build with the Clipper chip, the AT&T TSD-3600-E. Only a few thousand units were build and delivered to U.S. Government Agencies.
