3. © MATERNA GmbH 2012www.materna.com3 Contents  JMEDS modularity enables:  Staying lightweight  Going beyond DPWS  Extensibility  This presentation:  from improvements of the current (modularity)  over communication feature (network refreshing unit)  to solutions for more specific challenges

4. © MATERNA GmbH 2012www.materna.com4 JMEDS: Security Security  It is now possible to  sign discovery messages  use secure communication over TLS/SSL  authorize with username and password

5. © MATERNA GmbH 2012www.materna.com5 JMEDS: Security  Signed Discovery  using compact signature format  currently no canonicalization  Secure channel  TLS/SSL with or without credentials  Authentication  with X.509.v3 certificate  with username and password

6. © MATERNA GmbH 2012www.materna.com6 JMEDS: Security  CredentialInfo  main class for Security  includes various credentials credential info signing + ssl „LocalCertificateCredentialInfo“ (truststore, keystore, key alias) „RemoteCertificateCredentialInfo“ (certificate) username + password (http authorization) „LocalUserCredentialInfo“ „RemoteUserCredentialInfo“

7. © MATERNA GmbH 2012www.materna.com7 JMEDS: Security  Security key  essential class for getting devices and services  includes  discovery information (e.g. interface id and credential info)  credential info for secure channels  use to get  device reference  service reference

8. © MATERNA GmbH 2012www.materna.com8 JMEDS: Modularity Cleanup  lesser dependencies between modules  replaceability of modules  some modules are usable independently Modularity Cleanup

11. © MATERNA GmbH 2012www.materna.com11 JMEDS: Network Management  Updates automatically  interfaces  addresses  discovery domains  Manage changes  interface up, down, multicast status  address added, deleted  Announce changes to clients, devices, services, event sinks  bindings  auto bindings  discovery domains

12. © MATERNA GmbH 2012www.materna.com12 JMEDS: Network Management  Autobindings generate and manage bindings  IP discovery autobinding  input  interfaces  IP versions (v4 / v6)  credential info  output  IP discovery bindings (unsecure / secure)  IP communication autobinding  input  interfaces  IP versions (v4 / v6)  path  port  credential info  output  http / https bindings

13. © MATERNA GmbH 2012www.materna.com13 JMEDS: Android  Most of JMEDS is compatible with Android  Some modules have android specific implementations  ip_tcp_udp_android  platform_android  security_android Android

14. © MATERNA GmbH 2012www.materna.com14 JMEDS: Android  ip_tcp_udp_android  to find your wifi address automatically  to receive events if addresses or interfaces have changed (network refreshing unit)  platform_android  to access the android context from JMEDS  to use android specific folders like: assets, int, ext  security_android  to use keystores of type „BKS“ instead of „JKS“
