We need somone who has familiarity with Disk Encryption tools like true Crypt and Disk Cryptor and Boot Loader. Currently these softwares and have very limited support for Pre-Boot Authentication using keys stored on USB Security Tokens which are PKCS compatible like Aladdin Etoken Pro etc.
We have our own USB token with its own custom driver which ahs the capability to store passwords and key files and certificates. We want an open source disk encryption software (like truecrypt / diskcryptor but other suggestions are welcome) to support this USB token on pre boot authentication. SO the process should be that the suer would be able to logon to his machine upon bootup only when the required usb drive with his key file is inserted in the token.
Only consultants whoa re absolutely confident of this development should apply.
