    • An electronic voting system includes a vote security device (VSD), a user interface for presenting a ballot to a voter, and an audit trail printer operatively coupled to the VSD. The printer prints an audit trail ballot only in response to verifying encrypted and/or digitally signed messages received from the VSD that indicates the voter's ballot selections. The printer is structured to allow the voter to view but not access the audit trail ballot. The voter is able to accept or reject the audit trail ballot using the user interface. If the ballot is rejected, the VSD causes the printer to print a rejection indicator on the ballot, and if the voter accepts the ballot, the VSD causes the printer to print an acceptance indicator on the ballot. A digitally signed record of the voter's ballot selections is generated and stored.
    • 电子投票系统包括投票安全装置(VSD),用于向投票者呈现投票的用户界面以及可操作地耦合到VSD的审计跟踪打印机。 打印机仅打印审核跟踪投票,以响应验证从VSD收到的加密和/或数字签名消息,指示投票人的投票选择。 打印机的结构允许投票者查看但不能访问审核跟踪投票。 选民能够使用用户界面接受或拒绝审计跟踪投票。 如果投票被拒绝,则VSD会使打印机在投票上打印拒收指示符,如果投票人接受投票,则VSD会使打印机在投票上打印验收指示符。 生成并存储选民投票选择的数字签名记录。

    • Methods and systems that prevent completion of postdated financial transactions until the specified future date is provided. A portion of the information necessary to complete a financial transaction is encrypted utilizing an identity-based encryption (IBE) scheme. The encryption key used to encrypt the information is associated with the date on which the transaction is authorized to be completed. The encrypted information is provided to the payee. The issuing bank provides a daily decryption key that allows decryption of information encrypted using the key associated with the corresponding date. Thus, only when the maturity date of the transaction has arrived will the payee or depositing bank be able to obtain the decryption key that will decrypt the encrypted information necessary to complete the transaction. Since the encrypted information can not be decrypted until the date associated with the encryption key, the financial transaction can not be completed until such date.
    • 提供在指定的未来日期之前阻止完成后期金融交易的方法和系统。 使用基于身份的加密(IBE)方案来加密完成金融交易所需的一部分信息。 用于加密信息的加密密钥与交易被授权完成的日期相关联。 加密信息被提供给收款人。 开证行提供每日解密密钥,允许使用与相应日期相关联的密钥加密的信息进行解密。 因此,只有当交易的到期日到来时,收款人或存款银行才能获得将解密完成交易所必需的加密信息的解密密钥。 由于加密信息在与加密密钥相关的日期之前不能被解密,所以直到这样的日子才能完成金融交易。
