NCS-0347661CAREER: Efficient Cryptographic Protocols for Secure and Private Cryptographic TransactionsPI: Anna LysyanskayaA typical computer user performs a multitude of electronic transactions each day: reading e-mail, managing bank accounts, making on-line purchases, to name a few. Each of them must be secure: they should be carried out by authorized users only, and the information entered must be authentic. On the other hand, each transaction should be private: personal information or account balances should not become available without a user's explicit consent. Since data aggregation is simple to do, it is highly desirable to limit the information transmitted in each transaction to a bare minimum without compromising its authenticity.Cryptographic schemes that make this possible are the intended direct outcome of this research. This project investigates the security requirements of the basic protocols that a system for secure and private electronic transactions would comprise and develops efficient and provably secure digital signature schemes and other primitives that lend themselves to the design of such protocols. The chief method for achieving these results is to build upon existing highly theoretical foundations using practical buiding blocks.Since this project develops provable guarantees that personal information will not be abused, its broader impact is in protecting the privacy of computer users.

NCS-0347661职业生涯：安全和私人加密交易的有效加密协议PI：安娜Lysyanskaya一个典型的计算机用户每天执行大量的电子交易：阅读电子邮件，管理银行帐户，进行在线购买，仅举几例。 每一项都必须是安全的：只能由授权用户进行，输入的信息必须是真实的。 另一方面，每笔交易都应该是私密的：未经用户明确同意，个人信息或账户余额不应被公开。 由于数据聚合是简单的，它是非常可取的，以限制在每一个交易中传输的信息到最低限度，而不损害其真实性。使这成为可能的密码方案是本研究的预期直接成果。 本项目研究安全和私人电子交易系统所包含的基本协议的安全要求，并开发有效和可证明安全的数字签名方案和其他有助于设计此类协议的原语。 取得这些成果的主要方法是在现有的高度理论化的基础上，使用实际的积木。由于该项目开发了可证明的保证，即个人信息不会被滥用，其更广泛的影响是保护计算机用户的隐私。
