Today s topics l.jpg

Today’s Topics

  • CDX (Brief Overview)

  • CDX Approach to Addressing CROMERRR

  • Discussion


What is central data exchange l.jpg

What Is Central Data Exchange?


Cdx features l.jpg

CDX Features:

  • Multiple Submission Venues -> One Submission Point

  • Supports “Mass Customization”

    • Flexibility of submission formats (Web, XML, EDI)

    • Tailors submissions to specific customer

  • Uniformity Across Functions

    • registration, receipt, archiving, distribution, customer services, security

  • Leverages:

    • Widely-accepted PKI approach

    • Open Standards (XML, EDI)


Central data exchange l.jpg

Supported:

EPA reports that:

Require signature

Do not require signature

Can accept HTML, XML, Flat and EDI files that EPA has endorsed

Currently supporting TRI, Air emission inventory, PCS/IDEF and drinking water exchanges, retooling CDX exchange process for DMRs

Eventually expand ER across all EPA collections

Not Supported:

Multiple Digital Signature Software Solutions

HTML, XML, EDI, or flat file formats not accepted by EPA

EPA Confidential Business Information (not yet)

Encryption Software Solutions (not yet)

CBI Applications not currently “supported” (these may include certain FIFRA, TSCA, Acid Rain and other reports)

Central Data Exchange

CDX Processes:

  • Registration

    • CDX registration

    • Certificate Authority registration

  • Routine Submission of Forms

  • Renewal

Renewal Process

  • Requires users of the system to renew w. CDX every two years:

    • Must sign agreement with CDX that:

    • have not in any way compromised or delegated access to private key

    • no other evidence that any of these items (password, desktop software, account) have been compromised

  • Must also verify certificate with EPA’s CA


Cdx approach to key issues l.jpg

CDX Approach to Key Issues

David Schwarz, USEPA


How is submitter identified l.jpg

How is Submitter Identified?

Key Features:

  • Registration uses “Two-pronged approach”:

    • “In-house” Pre-screening by EPA through Registration Process

    • “EPA independent” identity proofing of individual by Certificate Authority (CA)

  • Requires “Wet-Ink” signature on Signature Agreement and Renewal Agreements

  • During routine submission:

    • CDX user identified by account password issued by CDX

    • “Digitally signed” submissions verified by EPA’s CA


How is the signature bound to the submission l.jpg

How is the Signature Bound to the Submission?

Key Features:

  • Data for signature is posted to users CDX web account in “human readable’ web form regardless of original format of data received (XML, EDI, flat).

  • When user is ready to sign form, must:

    • Agree to “Truth and Accuracy Statement” pop-up

  • Digital signature is applied to “format and content” of web form viewed

  • Signed data stream is transmitted through an encrypted SSL session.


How is the signature protected against unauthorized use l.jpg

How is the Signature Protected Against Unauthorized Use?

Features:

  • Signature can only be generated by:

    • accessing CDX account on EPA’s system

    • accessing private key on the user’s desktop system

    • accessing CDX software on user’s desktop

  • Software, private key cannot be shared with network or copied to another system

  • “Web” of out-of-band exchanges (acknowledgments, copy of records, etc.) provide means of detecting compromise


How is the signer made aware of the commitment he is bound to l.jpg

How is the signer made aware of the commitment he is bound to?

  • Initial “Wet Ink” Signature Agreement

  • “Reminders” during use of system:

    • Upon logging onto/off user’s CDX account

    • Upon invoking digital signature

    • Through receipt of acknowledgements, copy of records

  • Must “renew” agreement every two years


How is data protected in transit in storage l.jpg

How is data protected in transit? In storage?

  • “Digitally signed” data are submitted to EPA through SSL session with CDX

  • Password authentication, integrity checking and signature verification performed at CDX

  • Four-step archiving process captures “Snapshot” of signed data as it is received, authenticated, translated and presented back to user as copy of record.


The copy of record l.jpg

The “Copy of Record”

  • What is it?

    • electronic document as it was signed

    • the verified digital signature affixed

    • the date and time of receipt

    • and EPA’s digital signature of the entire content

  • Admissibility of Copy of Record

    • Must demonstrate authenticity of record and source

    • Must also consider “evidentiary weight” of COR


Copy of record l.jpg

Copy of Record

Features:

  • Copy of record “signed’ by EPA and provided back to user’s private account

  • Application of EPA’s digital signature prevents argument that data was altered

  • Centralized archiving and audit management functions ensure consistent process across submissions

  • Four-step archiving process ensures detailed historical record of document at each stage of CDX process
