This issue, the editor shares an article from the EUROCRYPT 2024 conference chapter on Advanced Public-Key Encryption, authored by researchers from Eindhoven University of Technology. This article abstracts the ElGamal encryption algorithm as a primitive called RRR relations (random self-reducible relations) and concludes that it cannot be proven to be OW-CCA-1 secure in the standard … Read more
In the digital world, we exchange information every day: online shopping payments, WeChat chats, online office work, and even scanning codes to take the subway… Behind these conveniences lies an invisible “security guard”—encryption algorithms. You may have heard of international mainstream algorithms like RSA and ECC, but today, we will discuss a “guardian of security” … Read more
Comprehensive Analysis of the Python Standard Library hashlib Module Encryption Algorithms It was a Wednesday night I will never forget; all user passwords in the production environment suddenly became invalid. After troubleshooting for half a day, we finally discovered that the issue stemmed from a seemingly harmless MD5 encryption— the intern had directly stored plaintext … Read more
The RSA encryption algorithm is the most commonly used asymmetric encryption algorithm, proposed by Ron Rivest, Adi Shamir, and Leonard Adleman in 1977. The name RSA is derived from the initials of their last names. It is the first relatively complete public key algorithm, which can be used for both encryption and digital signatures. This … Read more
Introduction In today’s digital age, data security has become one of the most severe challenges faced by enterprises and developers. Imagine your bank account information and personal privacy data as precious items placed in a transparent glass house, easily visible to anyone. This is why data encryption technology is so important—it acts like an invisibility … Read more
