Title: Protocols for preventing subliminal channels in hardware wallets Post by: Sergio_Demian_Lerner on June 20, 2013, 11:51:47 PM This is my last post about Firmcoin, regarding how to prevent covert channels while signing Bitcoin transactions and creating Bitcoin keypairs in hardware wallets, where the user may not fully trust the device.
I think this information can also be useful to other hardware wallets manufacturers, such as Trezor. If you find a vulnerability in any of these protocols, please notify me. No Subliminal Channel http://firmcoin.com/?p=52 Best regards, Sergio. |
