0 Introduction With the help of ECC (Elliptic Curve Cryptography), we can utilize the powerful capabilities of public key encryption while achieving the speed and security of symmetric encryption. Therefore, we gradually turn to practical scenarios, focusing on the following categories: (1). Public Key Key Exchange Protocols: ECDH (P256), ECDH (P384), ECDH (P521), X25519 and … Read more
Research and Realization of the RSA Encryption Algorithm Improvement YU Xin–hong,CHEN Qi,YAN Yu (Economy and Technology Institute, Anhui Agricultural University, Hefei, Anhui 230011, China) Abstract：The modular exponentiation and modular multiplication are essential elements to secure RSA algorithm. However, modular exponentiation has been so time-intensive that it impedes RSA algorithm’s application. Therefore, it is paramount to … Read more

The article first introduces the concept of searchable encryption, then discusses existing symmetric … Read more
If you ask me, which algorithm is the most important? I might answer “Public Key Encryption Algorithm“. Because it is the cornerstone of computer communication security, ensuring that encrypted data cannot be cracked. You can imagine the consequences if credit card transactions are compromised. Before getting into the main topic, let me briefly introduce what … Read more
For decades, computer scientists have sought to verify whether there exists an absolutely secure method to encrypt computer programs, rendering them uncrackable during use. At the end of 2020, several scholars successfully discovered an encryption method that prevents computer users from cracking programs by obtaining the code. Encrypting Program Code First, It Must Be Obfuscated … Read more
The COVID-19 pandemic has made remote working the new norm and brought the business world into a phase that is yet to be explored. Undoubtedly, due to the lack of face-to-face interaction and standard distance restrictions, many users have had to digitally sign some official documents over the past few years. To maintain the authenticity … Read more
Recently, I’ve been discussing addition and subtraction with regrouping within 20 in our activity group. We have progressed from understanding numbers within 100, practicing making ten, basic methods of regrouping, to the second round of learning numbers within 10, and now we’ve reached more strategies for calculations within 20. In the past couple of days, … Read more
The Tor browser, known for its anonymity, is striving to reach new heights in the pursuit of encryption keys. To generate encryption keys that are hard to crack, it is necessary to innovate and upgrade the random algorithms. A key is a parameter that is input data in the algorithm that converts plaintext to ciphertext … Read more
National encryption refers to the domestic encryption algorithms recognized by the National Cryptography Administration. The main algorithms include SM1, SM2, SM3, SM4, and the latest SM9. These algorithms are primarily used in domestic environments as recognized by the National Cryptography Administration. SM2 Algorithm: The SM2 elliptic curve public key cryptography algorithm is a public key … Read more
In May 2017, the WannaCry ransomware virus broke out globally, with some university students in mainland China reporting that their computers were attacked by the virus and documents were maliciously encrypted. The ransomware wreaked havoc, resembling a global internet disaster, causing significant losses to computer users. According to the latest statistics, over 100 countries and … Read more
