Since you can lock and unlock your door from anywhere in the world, what path do you think a message will follow from your phone to the Lockitron device? Since the device will work with \"any phone\" what might its interface be? It uses \"the same cryptographic protocols found in online banks\" - what might those be?

Since you rely on the Lockitron to secure your home, you are obviously trusting the device. Who and what else are you trusting? Make sure you consider not only deliberate attacks (violations) but also human error (lapses and slips) and natural events (power outages, etc.).

Do you think this device is a good idea? Why?

Solution

Lockitron uses similar protocols as we used in the banking sector. And it uses the same interface as used by the mobile banking for transfering the funds between various accounts. As in mobile banking, we can get account balance or even transfer balance using the sms, in the same way, even with the normal non android or non ios phone, we can unlock the door via sending a simple text message.

Lockitron uses the protocal named as TLS(Transport Layer Protocol), which is based on the public and private key cryptography. Here in this protocol, we required to exchange the keys for a perticular session. Keys are basically the random numbers for a perticular session and are known between the lockitron device and its server.

We can trust this device, and what else we can trust is described below:

1) As this lockitron uses banking protocols like TLS, which is a very secure protocol, that is why we can trust this TLS protocol.
2) As lockitron is bases on the powerful battery, so even in the case of power outage, we can use the battery and we can trust on it.
3) With this lockitron, we also can provide the permissions to other also, so in case of our absence also other person can unlock the door, so we can trust.

Yes, this is a good device due to following reasons:

1) Provides easiability, not required to keep the keys now
2) You can easily grant and revoke the access. Very useful in case of various organization, where we are giving access to users.
3) Run on powerful battery, which also notify us in case of battery is low. Thats good feature.
4) Even if some one is on door and knocking the door, then also this device notify, thats a cool feature.
