why we chose email
Why we chose Email
  • Concepts match the charter exactly
  • Implementations match the charter exactly*
  • Well understood by end users
  • Well understood by existing ISP industry
  • Well understood by existing vendors
  • Almost no new code - security agent only(same code that is a subset of other implementations)
  • ISPs can participate with their existing infrastructure and skill set
implementation overview
Implementation Overview
  • Really, it’s just email.
  • Security agent plugged in at any point in the pipeline between Client (Source) and Server (Source HISP)
  • Channels can be TLS-encrypted to protect routing information

key technologies
Key Technologies
  • Content Packaging: RFC 5322 + MIME
  • Addressing: endpoint@domain
  • Security & Trust: S/MIME
  • HISP-HISP Transport: SMTP(S)
  • Client-HISP Transport: SMTP, POP3, IMAP, MAPI, etc…
  • Certificate distribution: DNS CERT
structure metadata and innovation
Structure, metadata and innovation
  • Scalable structure
    • Body Text (always available, Individual Involvement)
    • Unstructured attachments (PDF)
    • Structured attachments (CCx, SCRIPT, etc.)
    • Explicit metadata MIME part (XDM)
  • Transport has proven itself over 20+ years
  • Innovate in the payload
security agent
Security Agent
  • S/MIME Sign and Encrypt of messages fully supports requirements of Security & Trust Workgroup
  • Certificate distribution by DNS CERT records
  • Scalable approach to PKI Management – starts easy as TLS, adds ability to scale down to individual
    • HISP manages certificates
    • Organization manages certificates
    • Individual manages certificates
  • Ability to use across implementations demonstrates the value of taking a transport-independent approach

reliable messaging
Reliable Messaging
  • Store and forward model is critical in a massively distributed network – because it is likely that destinations will be unavailable
    • Daily issues, upgrades, disaster, remote
  • Ability to route across intermediate hops will be important in a heterogeneous network
    • Corporate intranet gateways
why existing services matter
Why Existing Services Matter
  • Operations
    • Administration and provisioning
    • Backups
    • System health monitoring
    • Patch and upgrade process
  • Security history, minimal new attack surface
  • Multi-tenant issues worked out
  • Training and industry skill set
    • admin, NOC, customer service
  • Account support: quota management, billing, fraud detection, etc.

Since Tuesday
  • Secure Exchange Solutions has successfully sent and received NHIN-D messages using the SMTP implementation
  • A “desktop gateway” is available that enables any currently-live mail service (Gmail, Hotmail) to be used for NHIN-D messaging
    • We believe that with the SMTP solution, the bar for the largest webmail providers to offer NHIN-D service is low enough that we can expect to see offerings emerge.
