Head-of-Line Blocking in HTTP/2 Although HTTP/2 uses “frames”, “streams”, and “multiplexing” to eliminate “head-of-line blocking”, these techniques are applied at the application layer. However, at the lower layer, specifically in the TCP protocol, “head-of-line blocking” can still occur. TCP has a special “packet retransmission” mechanism to ensure reliable transmission. Lost packets must wait for retransmission … Read more

A Comprehensive Guide to Java Cryptography Architecture (JCA) and Java Cryptography Extension (JCE): Proper Usage of Java’s Built-in Encryption APIs for AES and RSA Years ago, while working on an e-commerce project, I discovered that users’ payment passwords were stored in plain text in the database. At that time, I was still naive, thinking that … Read more
Under the spotlight of the semiconductor industry, the MCU market has always been a battleground. Once, Texas Instruments (TI), and STMicroelectronics (ST) held the top positions in the industry due to their first-mover advantage and technological accumulation, pulling the strings of the entire industry. However, amidst the changing tides of the market, these two giants … Read more
Implementation of Encryption and Decryption Algorithms in Python (AES/DES) In modern information technology, the security of data has become increasingly important. Encryption algorithms are one of the key means to protect data privacy.
