Linear cryptanalysis can reveal information about a block cipher’s secret key.
线性密码分析可以揭示分组密码秘密密钥的部分信息。
By combining many known plaintext–ciphertext pairs, linear cryptanalysis exploits small statistical biases in linear approximations to recover key bits more efficiently than brute force.
通过结合大量已知的明文—密文对,线性密码分析利用线性逼近中的微小统计偏差,比穷举更高效地恢复部分密钥比特。
