Delo naj predstavi matematične osnove, potrebne za študij ElGamalovih javnih kriptosistemov, s povdarkom na digitalnih podpisih in eliptičnih krivuljah. Glavni cilj je predstaviti osnovne kriptografske protokole, ki se uporabljajo za evidenco poštnih plačil v digitalni dobi. Izdela naj se tudi testna implementacija ustreznega protokola/kriptosistema v programskem jeziku C.
