As the amount of digital information explodes, two new trends are emerging. First, data is increasingly being stored and managed in the "cloud", an untrusted trove of computing power and storage space for rent. Second, computer devices (e.g., cars, cell phones, medical implants) are everywhere and continuously exchanging messages.This research addresses the security issues raised by these trends by developing cryptography-based security solutions for processing large volumes of data in an untrusted setting. The main goals are (1) practical solutions for outsourcing sensitive computations to untrusted parties and (2) new methods for automatically converting a standard signature verification procedure into one that efficiently processes a batch of messages. An initial focus is to explore pairing-based solutions as a means of keeping the bandwidth overhead low. The primary technical challenges are designing formal models to capture the desired security guarantees, designing efficient systems and testing these systems in practical settings.

随着数字信息量的爆炸性增长，出现了两种新的趋势。首先，数据越来越多地被存储和管理在“云”中，这是一种不可信的计算能力和可供租用的存储空间。其次，计算机设备(如汽车、手机、医疗植入物)无处不在并且不断地交换消息。本研究通过开发基于密码学的安全解决方案来解决这些趋势带来的安全问题，以在不可信的环境中处理大量数据。主要目标是(1)将敏感计算外包给不可信方的实用解决方案；(2)将标准签名验证过程自动转换为有效地处理一批消息的新方法。最初的重点是探索基于配对的解决方案，以此作为保持低带宽开销的一种手段。主要的技术挑战是设计正式的模型以获取所需的安全保证，设计高效的系统并在实际环境中测试这些系统。
