Voting over electronic networks is one of the hardest challanges for trusted information processing. Trends to relay on secure hardware components are controversial due to design of malicious kleptographic technologies. Voting aplications are particularly sensitive to this kind of attacks - information leakage might be selective. Moreover, even when a voter can suspect existance of kleptocode, he might be forced to behave in a certain way.

Recent ideas to solve untrusted platform problem is to use a computer as a blind computing device that is unable to find out any information over voters choice and unable to change the vote, even at random, without the risk of  detection.
