We previously introduced that the forwarding performance of IPsec VPN varies with different encryption algorithms (using vSRX to test the performance differences of various IPsec VPN encryption algorithms), but does OpenVPN have this issue? First, we need to confirm the algorithm information used during the OpenVPN negotiation process. For the default configuration, the algorithm information … Read more
This article is an excerpt from a book produced by Zhihu: “Cats, Einstein, and Cryptography: Quantum Communication That I Can Understand” From Julius Caesar to Sherlock Holmes from Nazi leader Hitler to the father of AI, Turing… How did the ultimate code in the field of communication come into being? All of this must start … Read more
With cybercrime being so rampant, what should you do if your data is seen or even stolen by others? Data encryption is a common and effective security method and is the first choice for protecting enterprise data. But how do you encrypt data? Do you know what technologies are involved? Today, we will learn about … Read more
Author: Kelsey Houston-Edwards“Guangming Daily” (November 7, 2024, Page 14) The advent of future quantum computers will threaten the security of all classical encrypted information, and cryptographers are racing against time to develop encryption algorithms that can confound quantum computers. Rapidly Developing Quantum Computers Digital security experts worldwide are focusing on the Quantum Year Clock (Y2Q … Read more
Recently, a piece of news that originated from foreign media and was widely spread by domestic media has caused a stir in the mathematics community: the Riemann Hypothesis has been proven. Meanwhile, the blockchain community is also buzzing, suggesting that encryption algorithms may be compromised. Fields Medal and Abel Prize winner, Sir Michael Atiyah (April … Read more
DES Algorithm •DES stands for Data Encryption Standard, which is a block algorithm that uses a key for encryption. DES Algorithm Input Parameters •The input parameters for the DES algorithm are three: Key, Data, Mode. The Key is 7 bytes or 56 bits long, serving as the working key for the DES algorithm; Data is … Read more
