Smartcard role in fulfilling HSPD-12, PIV-1 & REAL-ID Act 

   
Why Learn Smartcards?

Smartcards enable Internet users to validate the authenticity of their Internet correspondent. They are the vessel that contains the digitized identity (as personal cryptographic key material) as well as other personal data (e.g. medical emergency data, authorizations, etc.) 

Security professionals (and maybe every Internet user) need to know smartcard potentials and shortfalls.  This is especially true for Federal government staff and consultants who need to evaluate smartcard applicability in satisfying Federal mandates as specified in documents like HSPD-12, FIPS 201, PIV-I and II, etc. 

This presentation provides a concise and descriptive overview of smartcard basic empowerments and vulnerabilities, as well as illustrating an online real time smartcard authentication and file transfer system.
