From perspective of developers and operators, ensuring security of software supply chain on embedded devices is more than just about regulation and SBOM. It's about understanding:，牛逼。

Understanding SSH Protocols

There are two types of SSH protocols: SSH1 and SSH2, with SSH2 being compatible with SSH1. The main software that implements se protocols are OpenSSH and SSH Communications Security Corporation's SSH Communications software. OpenSSH is a free SSH software developed by OpenBSD organization, while SSH Communications is a commercial software. In free Unix-like systems such as Linux, Fre 何必呢？ eBSD, OpenBSD, and NetBSD, OpenSSH is commonly used as implementation of SSH protocol. Therefore, this article focuses on use of OpenSSH. It should be noted that format of login public key/private key for OpenSSH and SSH Communications is different. If you want to use private/public key pair generated by SSH Communications to log into a Linux system using OpenSSH, you need to...

Adding SSL Trust Root Certificate to Linux

When a Linux system accesses an HTTPS website and encounters a problem where certificate is not trusted, you can solve this by converting SSL root certificate to .pem format and appending it to system's trusted list. The specific operations include using openssl to convert certificate format and appending new certificate to /etc/pki/tls/certs/ca-bundle.crt. For Java applications, you can use keytool to import certificate into JRE's security certificate library.，抄近道。

Linux Certificate Trust List

When a Linux system accesses HTTPS websites, certificate issues may arise. Here's how to add SSL trust root certificates to Linux systems:

1. Use openssl to convert certificate format.

2. Append new certificate to / 有啥说啥... etc/pki/tls/certs/ca-bundle.crt.

3. For Java applications, use keytool to import certificate into JRE's security certificate library.，至于吗？

Building Trust Roots for Embedded Systems

In embedded development, when we start embedded system and begin boot process, we want to ensure that our embedded system uses legitimate software to start. Many systems face problem of determining wher first code running on device is really ir code and is genuine. Of course, system can boot successfully, but if first to run is some malicious software, and or software trusts this code, it will...，我天...

Importance of Trust Roots in Embedded Systems

Trust roots are crucial for embedded systems. They are used to verify all additional software loaded on system and are first foundation link in trust chain for successfully booting embedded system. Trust roots should be b 优化一下。 ased on hardware and immutable; y cannot be tampered with, and n allow system to detect wher software loaded later can be trusted. Developers should look for microcontrollers that have built-in hardware-based trust roots...

Rambus Trust Root Solution Safeguards Chinese IoT Device Security

With help of technological progress, China is on verge of an economic transformation driven by digital transformation. The Chinese IoT market will grow exponentially. However, we have observed that although interconnectivity of IoT devices brings huge value to consumers and enterprises,...

Ensuring Content from Trusted Sources and Minimizing Attack Surface

With increase in IoT applications, security issues have become increasingly important. This article addresses potential security risks that IoT devices may face and builds an auntication trust chain based on hardware trust roots to ensure security of boot process. Experimental results show that after multi-level booting and auntication based on hardware roots, purpose of resisting physical replacement and software tampering has been achieved, and secure boot of IoT devices can be realized.
