This project is developing new techniques for manipulating sensitive data by exploring two related areas, computing on private keys and computing on authenticated data. Currently, a private key is an inert object that gives its holder the ability to perform a cryptographic operation on all messages, as may be the case when generating a signature. The project is exploring a new vision, in which computing on the private key itself creates new restricted private keys that can only perform restricted operations such as, for example, signing only some messages but not others. In the case of computing on authenticated data -- data for which integrity is important but secrecy is not -- the project is developing new tools to compute on such data and obtain authenticated results.The project is committed to the dissemination of research results, education of students, and outreach to industry. Overall, the proposed project will produce a next generation of technology for managing authenticated and encrypted data while advancing the field of applied cryptography and educating the next generation of researchers.

该项目正在开发处理敏感数据的新技术，方法是探索两个相关领域，即对私钥进行计算和对已验证数据进行计算。目前，私钥是一种惰性对象，它使其持有者能够对所有消息执行加密操作，就像生成签名时的情况一样。该项目正在探索一种新的愿景，即在私钥上进行计算本身创建新的受限私钥，这些私钥只能执行受限操作，例如，仅对某些消息进行签名，而不对其他消息进行签名。在对经过验证的数据进行计算的情况下--数据的完整性很重要，但保密性并不重要--该项目正在开发新的工具，以对这些数据进行计算并获得经过验证的结果。该项目致力于传播研究成果、教育学生和向工业界推广。总体而言，拟议的项目将产生下一代技术，用于管理经认证和加密的数据，同时推动应用密码学领域的发展，并培养下一代研究人员。
