Recover plaintext attack to block ciphers

TL;DR

This paper estimates the upper bound of 16-byte plaintexts for English texts, highlighting that block ciphers with block lengths up to 16 bytes are vulnerable to plaintext recovery attacks under known or chosen plaintext scenarios.

Contribution

It provides an estimation of the maximum number of plaintexts for English texts that can be recovered, emphasizing vulnerabilities in block ciphers with block sizes up to 16 bytes.

Findings

Upper-bound estimation for plaintexts in English texts

Vulnerability of block ciphers with block length ≤ 16 bytes

Implications for plaintext recovery attacks

Abstract

we will present an estimation for the upper-bound of the amount of 16-bytes plaintexts for English texts, which indicates that the block ciphers with block length no more than 16-bytes will be subject to recover plaintext attacks in the occasions of plaintext -known or plaintext-chosen attacks.
