So what about this new generation of firmwares that require signed updates; what do we know about the signature?
Is it a self-signed certificate or issued by some official certificate authority? Do they use the same cert for all tv models?
I could dedicate my computer running day and night (Intel Xeon W3520, 12 gig ram, 8 cores) to brute-forcing the certificate they use to sign the code.
What about the signed "games" that are encrypted witht the UDN of the device? Since we know the "key" it could be possible to find out what the code looks like once it is decrypted, perhaps even more info could be found by downloading the same "game" twice but encrypted with different UDNs. Can one deduce anything about the mechanism they use to sign/dedicate software like this?
