ChaCha20 vs AES: When Cryptographic Algorithms Meet the Security Power of TLS 1.3

Security is not additive, but subtractive—TLS 1.3 achieves this through a “minimalist” cipher suite, removing over 10 features (such as compression and renegotiation), and reducing the cipher suites from 37 to 5,AES-CBC was directly removed due to security risks. Meanwhile, the ChaCha20-Poly1305 algorithm has become the new favorite in the TLS protocol, gradually taking center … Read more

OW-CCA1 Security of the ElGamal Encryption Algorithm

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

Comprehensive Analysis of the Python Standard Library hashlib Module Encryption Algorithms

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

A Detailed Introduction to the RSA Asymmetric Encryption Algorithm: How It Works and Its Security

by
A Detailed Introduction to the RSA Asymmetric Encryption Algorithm: How It Works and Its Security

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
