TY - JOUR ID - 39188 TI - Constructing cryptographic definitions JO - The ISC International Journal of Information Security JA - ISECURE LA - en SN - 2008-2045 AU - Rogaway, P. AD - Y1 - 2012 PY - 2012 VL - 3 IS - 2 SP - 69 EP - 76 DO - 10.22042/isecure.2015.3.2.2 N2 - This paper mirrors an invited talk to ISCISC 2011. It is not a conventional paper so much as an essay summarizing thoughts on a little-talked-about subject. My goal is to intermix some introspection about definitions with examples of them, these examples drawn mostly from cryptography. Underpinning our discussion are two themes. The first is that definitions are constructed. They are invented by man, not unearthed from the maws of scientific reality. The second theme is that definitions matter. They have been instrumental in changing the character of modern cryptography, and, I suspect, have the potential to change the character of other fields as well.
