A variant of the approach described above but with very different reconciliation function and parameter choices is the work of Zhang, Zhang, Ding, Snook and Dagdelen in their paper, "Post Quantum Authenticated Key Exchange from Ideal Lattices."<ref>{{Cite web|title = Workshop on Cybersecurity in a Post-Quantum World|url = http://www.nist.gov/itl/csd/ct/post-quantum-crypto-workshop-2015.cfm|website = www.nist.gov|accessdate = 2015-06-06}}</ref> The concept of creating what has been called a DuffieDiffie-Hellman-like Key Exchange using lattices with a reconciliation function appears to have first been presented by French researchers Aguilar, Gaborit, Lacharme, Schrek, and Zemor at PQCrypto 2010 in their talk, "Noisy Diffie-Hellman Protocols."<ref>{{Cite web|title = https://pqc2010.cased.de/rr/03.pdf|url = https://pqc2010.cased.de/rr/03.pdf|website = pqc2010.cased.de|accessdate = 2015-06-06}}</ref> This work was then extended and put on a much more rigorous foundation by Peikert in his writings.<ref name=":0" /><ref name=":2">{{Cite journal|title = A Toolkit for Ring-LWE Cryptography|url = http://eprint.iacr.org/2013/293|date = 2013|first = Vadim|last = Lyubashevsky|first2 = Chris|last2 = Peikert|first3 = Oded|last3 = Regev}}</ref>
