摘要： A secure device for electronic voting is employs a write-once vote-recording cartridge, preferably based on an e-fuse array. The cartridge has two distinct modes of operation: write mode and read mode. When in write mode, the array can only be written—it cannot be read. When in read mode, the array can only be read—it cannot be written. The array starts out in write mode. When switched to read mode, it cannot be switched back. A hardware mechanism provides successful write confirmation. The e-fuse array is installed (like a cartridge) into a vote-recording device. The voting device has an encryption/authorization mechanism that combines polling parameters (entered by the polling authority) with user (voter) information (Voter ID confirmation, poll selections, etc.) to produce a “fuse string” to be written into the e-fuse array. Upon completion of each vote, the fuse string from is written to the array, with hardware confirmation of successful writing. When all polling is complete, the poll is “closed” by switching the e-fuse array to the “read” mode, which permanently disables any further modification of the array. The encryption used to generate the “fuse string” values for each voter (user) renders the e-fuse contents meaningless to anyone except an auditor with proper authorization. In order to read out the results of the poll, an auditor must enter “password” information to decode/decrypt the contents of the e-fuse array.
摘要翻译： 用于电子投票的安全装置采用一个写入一次的投票记录盒，优选地基于电子熔丝阵列。 墨盒有两种不同的操作模式：写入模式和读取模式。 在写入模式下，数组只能写入 - 不能读取。 在读取模式下，只能读取数组 - 不能写入。 阵列以写入模式启动。 当切换到读取模式时，不能切换回。 硬件机制提供成功的写入确认。 电子保险丝阵列（如墨盒）安装到投票记录设备中。 投票设备具有将轮询参数（由轮询当局输入）的轮询参数与用户（选民）信息（投票人身份确认，投票选择等）组合的加密/授权机制，以产生要写入e的“保险丝串” - 数组。 每次投票完成后，将熔丝串写入阵列，硬件确认成功写入。 当所有轮询完成时，通过将电子熔丝阵列切换到“读取”模式，轮询“闭合”，永久禁用阵列的任何进一步修改。 用于为每个选民（用户）生成“保险丝串”值的加密使得电子保险丝内容对于任何具有适当授权的审计师除外没有任何意义。 为了阅读投票结果，审核员必须输入“密码”信息来解密/解密电子熔丝阵列的内容。

摘要： The present invention provides a system, apparatus and method of programming via electromigration. A semiconductor fuse which includes a cathode and an anode coupled by a fuse link having an electrically conductive component, such as silicide, is coupled to a power supply. A potential is applied across the conductive fuse link via the cathode and anode in which the potential is of a magnitude to initiate electromigration of silicide from a region of the semiconductor fuse reducing the conductivity of the fuse link. The electromigration is enhanced by effectuating a temperature gradient between the fuse link and one of the cathode and anode responsive to the applied potential. Portions of the semiconductor fuse are selectively cooled in a heat transfer relationship to increase the temperature gradient. In one embodiment, a heat sink is applied to the cathode. The heat sink can be a layer of metal coupled in close proximity to the cathode while insulated from the fuse link. In another embodiment, the temperature gradient is increased by selectively varying the thickness of the underlying oxide layer such that the cathode is disposed on a thinner layer of oxide than the fuse link.
