to my limited knowledge, I have not heard people using ndnSIM to research on NDN security or privacy, other than DDoS.<br class="">
Maybe you can contact Zhiyi Zhang <zhiyi@cs.ucla.edu> directly to explore collaboration (he focuses on NDN security)<br class="">

Dear ndnSIM users,<br class="">
<br class="">
I am a researcher at University of Cambridge and I am looking for opportunities to collaborate on NDN security and privacy topics such as DDoS, content poisoning, trust etc., and open to other topics as well. ndnSIM users interested in collaboration please
email me at mohibi.hussain@cl.cam.ac.uk <mailto:mohibi.hussain@cl.cam.ac.uk>.<br class="">

Thanking in anticipation,<br class="">

Hello, Carl.<br class="">
<br class="">
Yes, I have some ideas.<br class="">
I just overloaded the operator new and delete to record every memory<br class="">
allocation and releasing.<br class="">
I assumed the memory allocation and releasing will keep a balance after a<br class="">
start-up time. So I just record all memory blocks allocated in a time<br class="">
interval [a,a + t1] but not released in [a, a + t1 + t2], where t2 is long<br class="">
enough that no cache entries or PIT entries created in [a, a+t1] will<br class="">
remain. The recored blocks are thought to be "leaked", though there may be<br class="">
references point to it.<br class="">
But it's a bit hard to find who allocated a specified memory block. I used<br class="">
to do it manually and it took me a lot of time. Recently I found I could<br class="">
use backtrace function to get the call stack and use scripts to convert<br class="">
address to line number. I'm writing it now. If you have interests in this<br class="">
trick, I can publish it to GitHub when it's finished before long.<br class="">

<br class="">
Does anybody have an experience of using a profiler with ndnSIM? I am<br class="">
having a memory leakage issue, which leads to having different errors per<br class="">
run. But apparently, the problem stems from a memory leakage issue.<br class="">
<br class="">
Any guidance appreciated.<br class="">
<br class="">
Thanks and regards,<br class="">
