  1. Authentication SystemwithResource Management Gregory Geosits Todd Little

  2. Overview • Authentication Server • Provide a means for a client to prove authenticity • Provide a means for a resource manager to verify a client’s authenticity • Implement a secure encryption algorithm

  3. Overview • Resource Manager • Provide a resource for an authentic client • Be able to verify a client’s authenticity

  4. Overview • Client • Connect to an authentication server and verify authentication • Connect to a resource manager, prove authentication, and obtain a resource

  5. Design Decisions • Communications via Java RMI • Each component of the system must be a different host • DES private-key encryption for authentication • 1-hour time window before authentication must be re-verified • 1 Interface for the Server and RM to share

  6. Security Attributes • Data Encryption Standard • Private Key Based • Implementation taken from ECE5477 • Method Usage • DES d = new DES(key); • Long e_value = d.encrypt(value); • Long d_value = d.decrypt(e_value);

  7. Security System Interaction

  8. Code Specifics • Server • Resource Manager • Client

  9. Server • Main ( ) Method • Set up RMI host • Bind host to RMI port 8182 • Create registry on that port • Initialize client names and private keys

  10. Server • Client_Connect ( ) Method • Parameters: String name, long e_key • Return Value: long encrypted_HOD

  11. Server • Resource_Connect ( ) Method • Parameters: String name, long e_data • Return Value: Boolean authenticated

  12. Server • Get_Hour ( ) Method • Parameters: none • Return Value: integer HOD

  13. Server • Resource_Deliver_Message ( ) Method • Parameters: String name, long data • Return Value: String message • Dummy Method

  14. Resource Manager • Main ( ) Method • Initialize RMI host • Bind host to RMI port 8183 • Create registry on that port

  15. Resource Manager • Resource_Deliver_Message ( ) Method • Parameters: String name, long data • Return Value: String message

  16. Resource Manager • Resource_Connect ( ) Method • Dummy Method • Client_Connect ( ) Method • Dummy Method

  17. Client • Main ( ) Method • Set up two RMI connections • Encrypt its own key • Authenticate to server • Retrieve message from Resource Manager • Display message

  18. Running the System • Server • Java Server • Resource Manager • Java Resource • Client • Java Client

  19. System Testing • 4 Scenarios • (Failure) Incorrect Name, Correct Key • (Failure) Correct Name, Incorrect Key • (Failure) Incorrect Name, Incorrect Key • (Success) Correct Name, Correct Key

  20. Enhancements • Private Key Transmission via Public Key Algorithm • Additional Resource Manager Functionality • Implementation in TCP

  21. Demonstration Thank You
