Mahmut Sinangil1, C. Thomas Gray2 Nvidia, Santa Clara, CA Nvidia, Durham, NC 1 2 On-chip oscillators are emerging as a critical circuit for improving the security of systemon-chips (SoCs). Many SoCs utilize an on-chip oscillator during boot-up, eliminating the need for external references (e.g., crystal) that could expose SoCs to vulnerabilities from external clock attacks. Additionally, on-chip oscillators are frequently employed for precise monitoring of critical system clocks [1]. Their functionality can be extended to detect clockglitch attacks, allowing a single validated and proven IP to serve multiple critical security applications. While several stable on-chip oscillators have been reported [2-6], they are unable to detect clock glitches. Conversely, works such as [7] and [8] can detect clock glitches but cannot provide a stable clock. This work proposes a new RC oscillator architecture that can detect clock-glitch attacks
