Participants: Anis, Ricardo, Jan, Gianluca, Antonio
Absent: Rodolfo, Omar, John Ko
Discussion Outline
Anis: Asks members to present their interests in the ZB WG
Gianluca: Interest in the security issues. Has been working in a key distribution mechanism over TinyOS, thus having expertise on TOS. They have been implementing the IEEE 802.15.4 Security Sub-layer. This work falls in the context of Cristiano's Master Thesis. For the moment, Cristiano has studied the standard, installed TinyOS 2.0.2 and JeongGul KO’s security support for TinyOS 2.x and experimented with this software. Now, he is “de-assembling” the TinyOS network stack. In particular he is looking into the tk154 interface, the CC2420_TK154 module, and how they interact.
Jan: Informs the group about the ongoing work on the 15.4 WG, and interface definitions proposed. There is still a technical problem remaining related to “message_t” abstraction (All fields in message_t must have fixed size, which may be a problem for 15.4 implementation) that is currently under discussion in the TinyOS devel list.
Anis: Proposes to use Open-ZB stack in the meanwhile and asks Ricardo to consider the possibility of creating a “black-box” implementation out of the current Open-ZB stack.
Ricardo acknowledges and will look into it.
Anis: Asks Gianluca if he knows about John’s security Implementation.
Gialuca: Is familiar with it and has already tried it. However there seems to be a technical problem that he already tried to discuss with John.
Ricardo: Asks Jan if there is an expected deadline for TinyOS core to consider the new “message_t” proposals.
Jan: Jan hopes to get more inputs from the TOS community. He stresses that this is a core issue…
Anis: Asks members to give inputs by email. According to the progress, the next meeting will be schedule no later than one month.
As agreed at the cots4qos meeting in Porto, As to the JGKO’s code, we had an exchange of emails with him. Here are the last news we have received.
Offline Participations
Rodolfo: presented what would be his contribution in a separate email. He is working on porting the mesh network implementation they did with TinyOS 1.x with open-zb code to the new TinyOS-2.x-based opne-zb code. He will also extend the approach in different aspects.
John: said that he is maintaining the CC2420 security stack in TinyOS 2.x and he would also like to provide insights and help in providing the security functionalities.
