comment Can RSA be securely used for “blind decryption”?
I might well be missing a reasonable use case for this protocol, though; it's getting late here and I really should get some sleep. What does seem clear to me, though, is that the ability to use Charlie as a decryption oracle is a major and rather fundamental security issue here.

comment What is matrix branching program?
It might help if you could make your question a bit more specific. Good questions here on Stack Exchange should be reasonably scoped, so that they can be answered in a few pages of text (or less). While I really don't know anything about the subject, I'd guess there's a good chance that "explain matrix branching programs to me" may be too broad a question for this site.

General programming questions are off topic here on Crypto.SE. You may be able to get answers to such questions on Stack Overflow.
