Duba wurin da ke ƙasa sannan ka amsa tambayar daga baya a cikin harshe ɗaya kamar yadda wurin yake:  Gabatarwa: Binciken ilimi mai zurfi a cikin cryptography kwanan nan ne; ya fara ne kawai a tsakiyar shekarun 1970. A cikin 'yan kwanakin nan, ma'aikatan IBM sun tsara algorithm wanda ya zama Tarayyar Tarayya (watau, Amurka) Data Encryption Standard; Whitfield Diffie da Martin Hellman sun wallafa mahimman yarjejeniyar algorithm; kuma an buga algorithm na RSA a cikin shafi na Martin Gardner na Scientific American. Bayan aikin su a cikin 1976, ya zama sananne don yin la'akari da tsarin ɓoye-ɓoye dangane da matsalolin ilmin lissafi waɗanda ke da sauƙin bayyana amma an sami wahalar warwarewa. Tun daga wannan lokacin, cryptography ya zama kayan aiki da aka yi amfani da shi a cikin sadarwa, cibiyoyin sadarwar kwamfuta, da tsaro na kwamfuta gaba ɗaya. Wasu fasahohin ɓoye na zamani na iya ɓoye maɓallan su kawai idan wasu matsalolin ilmin lissafi ba za a iya magance su ba, kamar su factorization na lamba ko matsalolin logarithm masu banbanci, don haka akwai alaƙa mai zurfi tare da ilmin lissafi mai mahimmanci. Akwai 'yan cryptosystems da aka tabbatar da cewa ba su da wata matsala. A daya-lokaci pad ne daya, kuma aka tabbatar da zama haka da Claude Shannon.
