Basically it depends what you call the off-card application, and whether you consider it trusted.
Anyway to answer your question, the private data managed by the card application does not need to be encrypted before being stored, because the storage can be considered safe.

Re: Power control for a smart card reader
No, there is no standard for doing that. If there is something, it has to be proprietary for the reader or possibly some generic USB power management API.

Re: How to find out what installed on javacard
There are many tools for you to list all the applets-AID on java card, such as GPShell , OpenSC, pyAPDUtool and so on. There are also an open source library to aim your goal. See this topic for the demo code. If you have the applet-AID that you wanna make selectable, you can select it by these tools.

Re: how compute Phi(N) of RSA?
In RSA computation, N=P*Q Phi(N) = (P-1)*(Q-1) When computing RSA STD, D<Phi(N) Phi(N) = (P-1)*(Q-1) = P*Q - (P+Q) + 1 According to N = P*Q, P + Q ≈ 2*(N^?) Phi(N) = N - 2*(N^?) + 1 How to compute N^?: According to X2 = [X1 + (N/X1)]/2, The first computation, X1 takes a radom number, compute X2. The...

Re: how to make a signature with java card and verify it
Simply use Signature and ALG_RSA_SHA_PKCS1 instead of SignatureMessageRecovery and ALG_RSA_SHA_ISO9796_MR on the Java Card side.
If you want message recovery you may have to use the Bouncy Castle library at the Java side.
