The best solution for your scenario would be to "Certify" the PDF that you send to your customer.  A certifying signature is a digital signature applied to a PDF (typically by the author of the document).  Adobe partners with various Certificate Authorities that provide "Certified Document Service" credentials.  If a PDF is certified by one of these credentials, the validation on the client side occurs seamlessly with no configuration required on the client as Acrobat and Reader ship with the Adobe Root Certificate installed.

For more information on the this, check out: http://www.adobe.com/security/partners_cds.html

Technically, you could certify a PDF with any credential, but you would need to distribute the certificate (public key) with instructions on how to install it and configure the trust settings in Acrobat or Reader.
