SUMMARY:CANCELLED Tutte Colloquium - Chloe Martindale
CLASS:PUBLIC
DESCRIPTION:Summary \n\nTITLE: Constructing broken SIDH parameters: a tale
  of De Feo\, Jao\,\nand Plut's serendipity.\n\nSpeaker:\n Chloe Martindale
 \n\nAffiliation:\n University of Bristol\n\nZoom:\n This event has been ca
 ncelled.\n\nABSTRACT:\n\nThis talk is motivated by analyzing the security 
 of the cryptographic\nkey exchange protocol SIDH (Supersingular Isogeny Di
 ffie-Hellman)\,\nintroduced by 2011 by De Feo\, Jao\, and Plut. We will fi
 rst recall some\nmathematical background as well as the protocol itself. T
 he 'keys' in\nthis protocol are elliptic curves\, which are typically desc
 ribed by\nequations in x and y of the form y^2 = x^3 + ax + b. Of importan
 ce in\nthis talk will be 'endomorphisms' associated to elliptic curves: th
 ese\nare functions that map an elliptic curve to itself which also satisfy
 \nsome nice properties.\n
