 Well, if you'd bought a CD set, you would have had access to a
 sinificant subset of the packages collection, fresh from a read-only
 medium that came from a trusted source.  Why don't you?

I'm not so sure about significant - you can't fit many of the 30GB of
i386/amd64 packages onto the CDs..

pkg_add does automatically verify signed packages or I do have to use a secure
link : https://ftp.openbsd.org/.../.../... ,or so.

First, please find a mirror. Very few people have any good reason to use
the main one at ftp.openbsd.org directly.

Second, you'll notice that each of the directories on the mirrors
contain a file called SHA256, which in turn contains the SHA256
checksums for all the files in that directory. Try grabbing the SHA256
along with the packages, verify that the signature checks out. Better
yet, fetch the SHA256 from the same directory on a different mirror.

Also, please read the FAQ, which contains a description of how it all
works. 

There's also a book coming out (
https://https.openbsd.org/cgi-bin/order?B10=1B10%2b=Add or
https://www.michaelwlucas.com/nonfiction/absolute-openbsd-2nd-edition )
that you should be able to buy when you return for your OpenBSD 5.3 CD
set that explains this and other matters OpenBSD quite well (note: that
endorsement comes from the book's tech editor).

 ports makefile are verifying downloaded (sources) file with checksum.

And you can download the ports makefiles via ssh cvs if you want
protection going forward.
