This is nothing new. A 'Lucas Sequence' is nothing more than a disguised
way of doing exponentiation in the twisted sub-group of a finite field
with p^2 elements. This is the sub-group that has order p+1, as opposed to
p-1, which is the group that RSA is based upon.

This has been well known for a long time among number theorists.

While I won't cry 'plagiarism', since the author may be unaware of
prior developments, for him to claim to be the 'inventor' is bogus
at best. It is NOT new.

>Not surprisingly, the author is attempting to patent the system

He should not be able to patent this, since what he has done was all
known before.
