California Bill Proposes Mandatory Kill-Switch On Phones and Tablets

alphadogg writes "Politicians and law enforcement officials in California will introduce a bill on Friday that requires all smartphones and tablet PCs sold in the state be equipped with a digital 'kill-switch' that would make the devices useless if stolen. The bill is a response to a rise in thefts of portable electronics devices, often at knife or gunpoint, being seen across the state. Already half of all robberies in San Francisco and 75 percent of those in Oakland involve a mobile device and the number is rising in Los Angeles, according to police figures. The trend is the same in major cities across the U.S. and the California bill, if it passes, could usher in kill-switch technology nationwide if phone makers choose not to produce custom devices for California. California Senate bill 962 says all smartphones and tablet PCs sold from Jan. 1, 2015, should have 'a technological solution that can render the essential features of the device inoperable when the device is not in possession of the rightful owner.'"

      You are correct that cryptography is not a cure-all to all problems, however, your post goes irrevocably wrong immediately after that. HSM and TPM chips are quite secure and well established. The example problems you suggest are in no way relevant to the conversation at hand since they deal with an entirely different use case of security. As dmbasso was kind enough to point out, I am referring to the use of asymmetric cryptography to allow secure validation of a private key being held remotely. Such cryptography is used all the time (any time you use an HTTPS page) to prove the exact same thing.

      The device merely has to hold the a public key for which the legitimate owner (or the vendor) has the private key. If the device is stolen and locked, it is trivial for an HSM to prevent unlock without the private key. It may be possible to circumvent the kill switch by yanking the HSM, but such an operation would likely exceed the black market cost of the majority of phones as it involves painstaking processes such as removing the silicon one layer at a time with a very carefully applied acid bath, and even then, the write once public key address space would be just as secure as any write once kill switch flag that could be implemented.

      To prevent re-activation of the kill switch itself (rather than the recovery mechanism) the switch could be tied in hardware to a similar challenge response against a private key held in the device's HSM. To "kill" the device, this private key would be wiped, preventing the device from starting. To re-initialize it, the private device key would be restored by looking for a key signed by the owner's private key.
