RSA SecurID teardown

RSA SecurID is a  two-factor authentication device. It gives out number that change depending on the time, and correct number is needed to log-in to sensitive systems (=one-time password functionality).  RSA SecurID 700 is a small key fob that connects easily to any key ring.

Here is  front panel of RSA SecurID 700. There is no numbers on the screen because battery was out of power.

Backside view with some ID codes hidden…

What is inside?

Closer look at the circuit board…

All the electronics was cast inside some resin that looked a bit hard to remove. So I don’t get to know on which tiny processor thus device runs with.

The battery is also inside the same resin (when battery runs out this device is useless waste).

Only exposed contacts seem to be those contacts that look like some kind of test/programming connector.
