A szerzők tanulmányukban az információbiztonság egy merőben új, minőségi változást hozó találmányával, a kvantumkulcscserével (QKD-vel – quantum key distribution) foglalkoznak. Céljuk az, hogy az újdonságra mint informatikai biztonsági termékre tekintsenek, és megvizsgálják a bevezetéséről szóló vállalati döntés során felmerülő érveket, ellenérveke...
