In muddooyinkii ugu danbeeyay, shaqaalaha IBM loogu talagalay algorithm in uu noqday Federaalka (ie, US) Data Encryption Standard; Whitfield Diffie iyo Martin Hellman daabacay ay key heshiis algorithm; iyo algorithm RSA waxaa lagu daabacay Martin Gardner ee Scientific American column. Ka dib markii ay shaqada 1976, waxa uu noqday caan ah in la tixgeliyo nidaamka cryptography ku salaysan dhibaatooyinka xisaabta in ay fududahay in gobolka laakiin waxaa laga helay adag tahay in la xaliyo. Tan iyo markaas, cryptography uu noqday qalab si ballaaran loo isticmaalo in isgaarsiinta, shabakadaha computer, iyo ammaanka computer guud ahaan. Qaar ka mid ah farsamooyinka cryptographic casriga ah oo keliya haysan kartaa furayaasha qarsoodi ah haddii dhibaatooyinka xisaabta qaarkood ay yihiin macquul ah, sida logarithm integerization ama logarithm go'doon, waxaa jira dhibaatooyin qoto dheer oo la xiriira; Claude Diffie iyo Martin Hellman daabacay ay key heshiis algorithm; iyo algorithm RSA waxaa lagu daabacay in Martin Gardner ee column Scientific
