Due to the uniqueness of embedded systems, there are many security threats. Firstly, because embedded systems have limited resources, with small RAM and ROM and limited processing speed, they cannot implement multiple security defense measures simultaneously, making them vulnerable to attacks. Secondly, the diverse deployment environments of embedded systems, such as industrial production environments, medical … Read more
Embedded systems are the core of modern electronic devices, and their security is crucial. These systems often contain sensitive data and critical functions, and if attacked, could lead to data breaches, system failures, or even physical damage. Therefore, security must be fully considered during the embedded design process. This article will delve into the security … Read more
