Why isn't this a bit of generic software that can run on anything?
- kube-system 4y agoAs I understand, it’s because they also have some physical security concerns. They operate kind of like a secure enclave I guess.
- astrange 4y agoIt's a "secure element" which is almost exactly like a "secure enclave". NFC payments also use them.
- fsckboy 4y agobut who is it secured from tampering, and secured to protect whom? The carriers? the customer? the NSA? Qualcomm? for encryption? for signing? ID/auth? "auth" of the above?
- bilekas 4y agoIt's a physical storage about the carrier. as far as i understand it's more convenient for carriers to onboard clients and also for users in general if a phone dies for example you can swap it into another. There are CDMA enabled phones that do not need a SIM card but they're a pain to transfer to another carrier. At least today.
- vasco 4y agoI don't need to swap a physical thing to log into my bank on another phone if my main one dies. I'm not sure why this is the answer.
- bilekas 4y agoBut imagine you have 2FA sms verification (horrible practice but prevalent) and your phone is dead. Sim swap out is helpful. I don't approve of it personally, but it's a legacy method anyway.
- AnthonyMouse 4y agoThat applies to a physical SIM card, but why is it needed for some eSIM/iSIM that can't be physically separated from the device? At that point it should be done entirely in software.
