Paper Review: Secure Electronic Voting for Mobile Communications

Authors: Xun Yi, Pietro Cerone, Yanchun Zhang
In 2006 X. Yi et.al has proposed a secure electronic election scheme based on blind signature for mobile communication environments. As one of the most important problems is the limitted resources on mobile devices, they have tried to increase the efficiency of the cryptographic operations by implementing a “Modular Square Root” technique. By this technique, a mobile voter needs to compute at most 7 modular multiplications plus one modular inversion. When compared to the previous protocols proposed for standart PCs such as Fujiko-Okamota-Ohta scheme, this schema requires much less computations in mobile voter thereby is more suited for implementation on portable communication devices with limited computational capacities and resources. Their schema meets completeness, soundness, privacy, unreuseability, eligibility, fairness and verifiability but not uncoercibility. And although they have proposed a secure schema, they have not mentioned anything about the implementation and other security issues i.e. how to prevent the security issues with the OS of those portable communication devices.
