Actually, we have a pending commit waiting to be merged into NDN-TLV specification: https://gerrit.named-data.net/c/NDN-TLV/+/4942
This commit defines the new NDN Signed Interest format.
Also, there is a corresponding implementation in ndn-lite library: https://github.com/named-data-iot/ndn-lite/blob/master/encode/signed-interest.h and https://github.com/named-data-iot/ndn-lite/blob/master/encode/signed-interest.c.

Hope it helps.

Best,
Zhiyi

Hello all,
I want to add signature for Interest packet. So I do some actions as follow:
Firstly, I add a member named m_signature in Interest.hpp.
Secondly, I add set and get function for this field of m_signature in interest.hpp.
Thirdly, I change the function of wireEncode and wireDecode in interest.cpp to encode and decode it.
Finally, I  add a value for m_signature  in ndn-consumer.cpp.
However, when I run the test program of ndn-simple,it shows the folloing errors，is there anyone can help me to resolve it.

terminate called after throwing an instance of 'boost::exception_detail::clone_impl<boost::exception_detail::error_info_injector<ndn::Interest::Error> >'
what():  unrecognized element of critical type 4294967295

Thanks a lot.
