The Election Commission has thrown down the gauntlet at political parties, asking them to crack its Electronic Voting Machines (EVM). The poll panel has set June 3 as the date for the hackathon to let opposition political parties prove their contention that the EVMs used in the February-March assembly elections were, or could be, tampered with."EVMs are not hackable as these are stand alone machines and not connected to internet and/or any other network," CEC Nasim Zaidi said at a conference explaining why it was tamper-proof. But cracking the EVMs comes with riders and EC has ensured parties won't have it that easy. Here are EC's terms and conditions:1) Only those parties, national and regional, that took part in the recently concluded assembly elections can hack the EVMs2) Each party can appoint 3 people each to crack the EVMs.3) The EVMs need to be picked from EC's warehouses in Delhi at parties' own cost.4) If a party fails to report at the alloted time without prior intimation or approval, their challenge shall be cancelled.5) Parties who want to crack the EVMs have to write to the EC by May 26, 5 pm with details of the members.6) Each political party will get to pick at least 4 EVMs of their choice from any 4 polling stations out of the five poll-gone states. EVMs involved in the election petition or those sealed will not be allowed in the hackathon.7) If the EVM becomes non-functional after the tamper attempt or if the tamper result is same as the one put out by EC or if the challenger violates the rules set, the challenge will be struck down.
