#Online voting a step closer thanks to breakthrough in security technology Taking inspiration from the security devices issued by some banks,

'The main advantage of this system is that it splits the security between the independent security device and a voter's computer or mobile device.

whereas the independent security device has a much, much smaller code base and is not susceptible to viruses.'Online voting carries a strong security requirement because of the possibility of undetectable interference in an election by foreign governments, criminal gangs,

and detect malware by using a separate security device. But the system achieves even greater security than those used by banks by allowing for the possibility that the security devices themselves have been manufactured under the influence of a hostile adversary.

Paradoxically, the researchers succeed in proving that even if a hostile adversary controls the entire computing infrastructure,
