Every standard (GSM network) phone has a Sim card that is doing some encryption with hardware protected keys. A Sim card for the GSM network.
Trying to use it for general encryption might have problems and is more often discussed than done.
- microcolonel 9y agoAhh, just say SIM. GSM is the network, SIM is the module. SIMs are basically just javacards, so having custom crypto applications on them is no big deal, but you need some control of the SIMs your users will want to use in your device for it to be practical.
- yayana 9y agoGoogle is US focused so they presumably still deal with non GSM networks and the possibility of running a fingerprint without a gsm standard SIM. * I.e. there are a lot of issues for Google generalizing encryption via some user provided sim as datails come up. So maybe he is referring to an entirely different crypto module.
