Can OTP be used with RSA Considering that a PKI has already been established, why can't we use RSA to send the One Time Pad instead of using AES?

It makes sense to me since:


A trusts the CA which is providing the identity of B
and vice versa
A obtains the public key of B from the Certificate and uses it to encrypt the pad
B decrypts the message and obtains the pad


Is this possible?
The one time pad can be used to provide perfectly secure encryption, given fully random key stream. Of course this key stream needs to be kept perfectly secure for it to be considered fully random.

Nether RSA nor AES can be used to protect a one time pad, because the one time pad would rely on RSA and AES to be secure. Neither RSA nor AES are perfectly secure, and neither can even be proven to be secure - as far as we know.

This prohibits distributing a one time pad with either RSA or AES; you are better off just using RSA / AES directly, for instance using a hybrid cryptosystem with AES in counter mode or any authenticated mode.
