Introduction Traditional hair dryers often use brushed motors, which have lower speeds, simple structures, and driving methods, resulting in lower overall costs. However, these conventional hair dryers produce less airflow, and to ensure effective drying, they must rely on high-power heating elements to increase the air temperature, which can be quite hot during regular use … Read more
Source: Diao Si Java Programmer (ID: java_diaosi) Information encryption technology utilizes mathematical or physical means to protect electronic information during transmission and storage to prevent leakage. Due to the illegal copying of computer software, communication leaks, and threats to data security, issues of decryption and piracy have become increasingly severe, even leading to international disputes. … Read more
Security Design Solutions for IoT Applications Driven by PLC Function Block Diagrams A few days ago, a friend involved in factory automation rushed to me, saying that their temperature control system inexplicably activated in the middle of the night, nearly causing a safety incident. After investigation, it was found that their newly launched remote monitoring … Read more

Introduction to HTTP and HTTPS HTTP (HyperText Transfer Protocol) is a stateless communication protocol commonly used for transmitting hypertext (such as HTML pages) between clients (like browsers) and servers. However, it is merely a one-way communication protocol, and data is not encrypted during transmission, making it susceptible to man-in-the-middle attacks. Stateless means it … Read more
In the field of information security, cryptography plays a crucial role by encoding and decoding information to ensure its confidentiality, integrity, and authenticity. Symmetric encryption is a major branch of cryptography, characterized by the use of the same key for both encryption and decryption. Among the many symmetric encryption algorithms, the Advanced Encryption Standard (AES) … Read more
