Abstract: General image encryption schemes transform plaintext images into snowflake-like ciphertext patterns through efficient cryptographic permutation and confusion primitives. However, these ...

Basic Cryptography Background Cryptography is the process of converting ordinary information (i.e., plaintext) into a scrambled unintelligible mess (i.e., ciphertext). This conversion process is ...

Involves decrypting two different pieces of ciphertext using two different methods (KPA and COA) to find the encryption keys and the original plaintext messages.

This project implements a simple XOR-based encryption and decryption algorithm. XOR encryption is a fundamental cryptographic technique that uses the XOR (exclusive OR) operation to encrypt and ...

Meanwhile, existing ciphertext search schemes often overlook lightweight computing paradigms and ... Security analysis demonstrates that the SFMS-CC scheme withstands choose plaintext attack, ...

The results were surprisingly chilling. SIGN UP for Plaintext to read the whole thing, and tap Steven's unique insights and unmatched contacts for the long view on tech. Like it or not ...

SIGN UP for Plaintext to read the whole thing, and tap Steven's unique insights and unmatched contacts for the long view on tech. Consider the email from one recent would-be codebreaker.

With the development of smart grid and the diversification of their applications, privacy-preserving multi-dimensional data aggregation has been widely studied because it can analyze users’ ...
