As explained in the SDK 1.1 user guide, the unlock service midlet will replace ISD (Issuer Security Domain) keys by public keys but I wonder me how we can install applications in the secure element without breaking the chain of trust?
So I have two questions :
- Is or Will it be possible with the unlock service midlet to get private keys instead of public keys in order to have the ability to install another applet later
- If we can't realize the first solution, after unlocking the secure element with public keys, will it be possible to lock it again with private keys
Thanks in advance
