  2. Abstract This presentation provides an update to an open source project of the SAE protocol used in TGs. Dan Harkins, Aruba Networks

  3. Reference Implementation of SAE • Free, open source implementation of the password-based key exchange used in 802.11s. • Project at SourceForge– www. sourceforge.net • Project name is “authsae” • Anonymous CVS access to source code is available • “developer” status, allowing write-access to source code repository requires OK by admin (i.e. me) • Written in C. • Supports elliptic curve groups (no prime modulus groups yet). Uses OpenSSL library. • Supported OSs are FreeBSD and Linux (limited support). Dan Harkins, Aruba Networks

  4. Changes and Current Status • Code supports multiple applications communicating over the “loopback” interface • Loopback simulates the “air”– every packet sent is also received. • Allows for simulations of full NxN mesh in a controlled environment. Each “app” acts as a mesh point. • Compliant with version 4.01 of TGs draft :-) • Assumes several comments on state machine and message construction will be accepted. • Atheros radio support (after slight kernel modification) under FreeBSD. • Loopback interface support under Linux and FreeBSD. • Includes a “monitor” app to sniff SAE frames. Dan Harkins, Aruba Networks

  5. Benefits of Reference Implementation • A working state machine for SAE • Easy to make changes to see what happens. • Configure open threshold, negotiate groups, etc. • The SAE component is OS-independent • The OS-specific component is “meshd”. Three defined APIs between “meshd” and “sae”. • This allows easy porting of SAE code to new operating systems (like yours!) by just supporting the APIs. It may require limited modification– some include files, possibly crypto library calls if openssl is not used. But the core SAE code will easily port. • No egregious licensing. Virus free! • GPL will not infect the rest of your codebase! • Code is released under the BSD license meaning it can be changed and used how you want and all you need to do is provide proper attribution. Dan Harkins, Aruba Networks

  6. SAE Reference Implementation • Complete SAE implementation • Cost-free and virus-free • Easily portable to your OS • Go to www.sourceforge.net • Project name authsae Check it out! (if you do, please let me know) Dan Harkins, Aruba Networks
