What Hellman and Diffie proposed was quite revolutionary -- use one-way functions or mathematical formulas that are easy to compute in one direction but impossible to do in the reverse unless one knew how they were constructed in the first place.
Ano Hellman at Diffie iminungkahing ay lubos na rebolusyonaryong - gamitin ang isa-paraan function o matematika pormula na madaling compute sa isang direksyon ngunit imposibleng gawin sa reverse maliban kung ang isang alam kung paano sila ay itinayo sa unang lugar.
