proposed solution to known plain text vulnerability

["N. E. Johnson" <NEJohnson@xxxxxxxxxxx>]

Here is a proposed solution to known plain text vulnerability.

Create and store a segment of random data equal in size to the data being encrypted.

XOR the user data with stored random data.

Encrypt both the random segment and the user data with conventional block cipher 
methods.

Since the user data was XORed with randomness, reminiscent of OTP. This would 
prevent usage of a precomputed dictionary against known plain text.

Obviously, users of this solution double their storage requirements.
