物联网设备的能耗是一个非常重要的问题。出于这个原因，已经开发了许多技术来允许物联网节点了解可用能量的数量。当缺少能量时，设备停止并保存其状态。其中一种技术是上下文保存，依赖于使用非易失性存储器（NVM）来存储和恢复设备的状态。然而，就物联网设备处理安全性而言，这些信息可能成为攻击的目标，包括篡改和窃取机密数据。在本文中，我们提出了一种安全上下文保存（SECCS）方法，该方法提供了一个上下文保存过程和一个易于在片上系统（SoC）内部实现的硬件模块。这种方法为保存到目标NVM中的所有CPU内容提供了机密性和完整性。
Energy consumption of IoT devices is a very important issue. For this reason, many techniques have been developed to allow IoT nodes to be aware of the amount of available energy. When energy is missing, the device halts and saves its state. One of those techniques is context saving, relying on the use of Non-Volatile Memories (NVM) to store and restore the state of the device. However, this information, as far as IoT devices deal with security, might be the target of attacks, including tampering and theft of confidential data. In this paper, we propose a SECure Context Saving (SECCS) approach that provides a context saving procedure and a hardware module easy to implement inside a System on Chip (SoC). This approach provides both confidentiality and integrity to all the CPU content saved into the target NVM.
