项目摘要

Conventional volatile memories such as static random-access memory (static RAM) suffer from significant leakage power whereas conventional storage class non-volatile memories (NVM) such as flash memory suffer from higher write energy, poor performance and low endurance. Emerging NVMs such as, spin-transfer torque RAM (STTRAM) and resistive RAM (ReRAM) offer zero leakage, high-density, scalability and high endurance. Due to these promising aspects, emerging NVMs are already being commercialized by several companies. Although NVMs can reap energy and performance benefits they may face new security challenges. This research will expose and address the security and privacy threats to NVMs.This research will (i) identify the vulnerabilities of NVMs by understanding the interaction between device properties and ambient parameters, (ii) identify integrity threats such as tampering and row-hammering, (iii) propose methods of real-time attack sensing, (iv) develop circuits and system-level techniques such as nano-shielding and memory access control to ensure data integrity, (v) identify privacy threats such as unauthorized access and fault injection attack to extract secret data, and (vi) propose quantized memory, intelligent erasure and camouflaging of side channels to ensure data privacy.The success of this research may lead to wider adoption of NVMs in security-critical sectors such as healthcare and banking. With growing acceptance of emerging NVMs in automobiles and solid state drives this work may have more immediate benefits, such as enabling on-chip, NVM-enabled, low-power devices, as well as spreading cybersecurity literacy. All publicly released data will be made available after the project and will be posted at http://www.logics.psu.edu.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

诸如静态随机存取存储器（静态RAM）之类的传统易失性存储器存在显着的泄漏功率，而诸如闪存之类的传统存储类非易失性存储器（NVM）则存在写入能量较高、性能差和耐用性低的问题。自旋转移矩 RAM (STTRAM) 和电阻 RAM (ReRAM) 等新兴 NVM 具有零泄漏、高密度、可扩展性和高耐用性。由于这些有前途的方面，新兴 NVM 已被多家公司商业化。尽管 NVM 可以获得能源和性能优势，但它们可能面临新的安全挑战。这项研究将揭露并解决 NVM 的安全和隐私威胁。这项研究将 (i) 通过了解设备属性和环境参数之间的相互作用来识别 NVM 的漏洞，(ii) 识别完整性威胁，例如篡改和行锤击， (iii) 提出实时攻击感知方法，(iv) 开发电路和系统级技术，例如纳米屏蔽和内存访问控制，以确保数据完整性，(v) 识别隐私威胁，例如未经授权的访问和故障注入攻击提取秘密数据，以及(vi) 提出量化内存、智能擦除和侧通道伪装以确保数据隐私。这项研究的成功可能会导致 NVM 在医疗保健和银行等安全关键领域得到更广泛的采用。随着汽车和固态硬盘中新兴 NVM 的接受度不断提高，这项工作可能会带来更直接的好处，例如支持片上、支持 NVM 的低功耗设备，以及传播网络安全知识。所有公开发布的数据将在项目结束后提供，并将发布在 http://www.logics.psu.edu。该奖项反映了 NSF 的法定使命，并通过使用基金会的智力价值和更广泛的评估进行评估，被认为值得支持。影响审查标准。
