I am looking for an authentication mechanism that works best with low memory, low computing power devices. I came across a paper "A Practical Zero-Knowledge Protocol Fitted to Security Microprocessor Minimizing Both Transmission and Memory" which is released in 1988.
Couldnt find any recent papers. Is it the best one or am I missing some ?
I have a case where I have few processors connected to a gateway processors. I can send upto 64 bits of data at a time. Computing power is low in the sense that I cant employ something like AES-128 algorithm in all chips. I also need to minimize the number of bits of data send for authentication
