CAREER: Cryptography for Secure Outsourcing

个人和组织通常信任第三方提供商来保存敏感数据，从而使其面临暴露的风险。 虽然数据可以使用对提供商保密的密钥进行加密，但由于管理加密的不便和成本增加，这种情况很少发生。 该项目将开发高效、便捷地处理加密数据的技术。 特别是，它将能够搜索加密数据（这是当前部署的加密所阻止的），并在加密数据上有效运行任意程序。这项工作的更广泛影响将包括可搜索加密和其他外包技术的新实用技术，以及这两种原语的基础结果，以加深对其潜力的了解。该项目将开发可搜索加密的新技术，以支持更灵活和可用的搜索，提高效率，并通过向恶意服务提供商泄露更少的信息来增强安全性。 特别是，它将把加密搜索的密码学研究与成熟的信息检索技术统一起来。 拟议的工作将研究遗忘 RAM 的构造和基础。 它将开发基本的新下限，以绘制不经意 RAM 的可能性景观，并设计和分析新的结构。有关更多信息，请参阅该项目网站：http://www.research.rutgers.edu/~dc789/career/

Individuals and organizations routinely trust third party providers to hold sensitive data, putting it at risk of exposure. While the data could be encrypted under a key that is kept secret from the provider, it rarely is, due to the inconvenience and increased cost of managing the cryptography. This project will develop technologies for working with encrypted data efficiently and conveniently. In particular, it will enable searching on encrypted data, which is prevented by currently deployed encryption, and running arbitrary programs efficiently on encrypted data. The broader impact of this work will include new, practical techniques for searchable encryption and other outsourcing technologies, and foundational results for both primitives to deepen understanding of their potential.This project will develop new techniques for searchable encryption to support more flexible and usable searching, to improve efficiency, and to enhance security by leaking less information to a malicious service provider. In particular, it will unify the line of cryptography research on encrypted searching with well-developed information retrieval techniques. The proposed work will investigate constructions and foundations of oblivious RAM. It will develop fundamental new lower bounds to map the landscape of possibilities for oblivious RAM, and design and analyze new constructions.For further information see the project web site at: http://www.research.rutgers.edu/~dc789/career/
