Riana Pfefferkorn, a Cryptography Fellow at the Center for Internet and Society at Stanford Law School, has published a whitepaper on the risks of so-called "responsible encryption". This refers to inclusion of a mechanism for exceptional access by law enforcement to the cleartext content of encrypted messages. It also goes by the names "back door", "key escroe", and "golden key".
Federal law enforcement officials in the United States have recently renewed their periodic demands for legislation to regulate encryption. While they offer few technical specifics, their general proposal—that vendors must retain the ability to decrypt for law enforcement the devices they manufacture or communications their services transmit—presents intractable problems that would-be regulators must not ignore.
[...] While the details are unclear, Deputy Attorney General Rosenstein’s and FBI Director Wray’s respective proposals for “responsible solutions” on encryption both appear to call for mandatory key recovery to guarantee law enforcement exceptional access to encrypted data. This kind of exceptional-access scheme presents significant, intractable information security, economic, and public-safety risks. Yet it cannot guarantee that law enforcement will actually be able to obtain plaintext messages or device data in all cases.
However, with all that said, a lot more is said than done. Some others would make the case that active participation is needed in the democratic process by people knowledgeable in use of actual ICT. As RMS has many times pointed out much to the chagrin of more than a few geeks, "geeks like to think that they can ignore politics, you can leave politics alone, but politics won't leave you alone." Again, participation is needed rather than ceding the whole process, and thus its outcome, to the loonies.
