What is about the CryptoNote/Bytecoin authors? As we know those names from cryptonote.org are likely to be pseudonyms.
But who is hidden behind it? You know, I made a kind of "literature review" and that's my list of (possible) CN authors:
Ring signatures, of course, is the main CN feature. So I started with it. Ring signatures were invented by Ron Rivest, Adi Shamir, and Yael Tauman, and introduced in 2001
(1). But their concept was far from what we see in CN now, so I went further.
Patrick P. Tsang and Victor K. Wei presented their paper "Short linkable ring signatures for e-voting, e-cash and attestation" in 2004
(2). Yes, they wrote about LINKABLE signatures, but they undoubtedly were able to rework their concept till 2012.
Next paper gained my attention is "Traceable Ring Signature" by Fujisaki and Suzuki released in 2006
(3) . This system is similar to blind signature developed by David Chaum (another possible CN inventor?) and it "may be used as a very primitive on-line anonymous e-cash system". I should admit this paper is very close to CN whitepaper in mathematics.
My other guess is Matthew Franklin and Haibin Zhang with "Unique Group Signatures" study (2012)
(4). They presented a number of unique group signature schemes under variety of security models.
Ok, go on. One-time addresses used in CN for transactions' unlinkability are also not super-new idea. Here you can see the discussion started by
ByteCoin user (5) in April, 2011. One more is here
(6) and there
(7) . It's August and December, 2012. What if one of those who had discussed unlinkability is CN developer?
Then there are a lot of people who didn't believe in Bitcoin Anonymity from the beginning
(8 ) . I think one of them may be potential BCN/CN inventors. Fergal Reid and Martin Harrigwere were the first, who started to work on it in 2011
(9) and later Israeli mathematicians and cryptographers Dorit Ron and Adi Shamir made Quantitative Analysis of the Full Bitcoin Transaction Graph
(10). It's dated May 2012, so they had enough time to work on CN/BCN too.
Regarding CN Pow I was back to Adam Back again. However I've also found Mart n Abadi, Michael Burrows, and Ted Wobber who worked on Moderately hard, memory-bound functions as early as 2003
(11) and Cynthia Dwork, Andrew Goldberg, and Moni Naor who also wrote about memory-bound functions in 2003
(12).
To be honest, that's my short list of possible CN authors. What do you think of it?
Nice summary, thanks! To be honest this ByteCoin user is very suspicious.
However Colin Percival also worked on stronger key derivation via sequential memory-hard functions:
