S-DES (Simplified Data Encryption Standard) is a pedagogically oriented, reduced-complexity variant of the full DES algorithm. It operates on 8-bit plaintext blocks with a 10-bit secret key, providing a tractable environment for studying fundamental cryptanalytic methods \u2014 linear cryptanalysis, differential cryptanalysis, and combined linear-differential cryptanalysis. This paper analyzes the architectural design, subkey generation mechanism, permutation logic, and security properties of S-DES. The cipher\u2019s vulnerability to brute-force exhaustive search and differential cryptanalytic attacks is examined in detail, and its potential use as an image encryption primitive \u2014 enhanced through chaotic key generation \u2014 is evaluated experimentally. The study concludes that, while S-DES is cryptographically inadequate for practical deployment, it constitutes a highly effective educational tool for illustrating the core principles of symmetric block cipher design.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t
