写一段java语言实现混沌加密算法完成文本加密

在Java中，混沌加密算法通常是通过模拟混沌系统来生成随机密钥，然后使用这个密钥流对文本进行异或(XOR)操作。以下是一个简单的示例，我们将使用Lorenz Attractor混沌系统和一个字符串作为输入进行加密。注意，这仅用于教学目的，实际生产环境中应当采取更为安全的方式来处理混沌加密，因为它不是标准的加密算法。

import java.util.Random;

class LorenzAttractor {
    private static final double SIGMA = 10.0;
    private static final double BETA = 8.0 / 3.0;
    private static final double RHO = 28.0;

    public double[] iterate(double[] state) {
        double s = SIGMA * (state[1] - state[0]);
        double r = RHO * state[0] - state[1] - state[0] * state[2];
        double z = state[0] * state[1] - BETA * state[2];

        state[0] += s;
        state[1] += r;
        state[2] += z;

        return state;
    }
}

public class ChaoCryptor {
    private LorenzAttractor lorenz;
    private double[][] initialStates;
    private Random random;

    public String encrypt(String text, int keyStreamLength) {
        this.random = new Random();
        this.lorenz = new LorenzAttractor();

        // 创建初始状态数组，这里假设每个字符映射到一个双精度数值
        initialStates = new double[text.length()][3];
        for (int i = 0; i < text.length(); i++) {
            char c = text.charAt(i);
            initialStates[i][0] = c;
            initialStates[i][1] = c;
            initialStates[i][2] = c;
        }

        // 生成密钥流
        double[][] keyStream = generateKeyStream(keyStreamLength);

        // 对文本进行异或加密
        StringBuilder encryptedText = new StringBuilder(text.length());
        for (int i = 0; i < text.length(); i++) {
            encryptedText.append((char) ((text.charAt(i) ^ keyStream[i][0]) & 0xFF));
        }

        return encryptedText.toString();
    }

    private double[][] generateKeyStream(int length) {
        double[][] stream = new double[length][3];
        for (int i = 0; i < length; i++) {
            stream[i] = lorenz.iterate(initialStates[random.nextInt(initialStates.length)]);
        }
        return stream;
    }
}

// 使用示例
public static void main(String[] args) {
    ChaoCryptor cryptor = new ChaoCryptor();
    String plainText = "Hello, World!";
    String encrypted = cryptor.encrypt(plainText, 100); // 生成100个混沌状态作为密钥流
    System.out.println("Encrypted Text: " + encrypted);
}
