In this digital information era, data transmitted over internet is vulnerable to several types of attacks. To preserve our information over internet, it is necessary to use some cryptographic methods. advanced encryption standard is a strong symmetric, non-fiestel cryptographic algorithm which preserves the information transmitted in internet from piracy or attacks. In this research article, a new and an efficient key dependent AES algorithm is presented for securing the data over internet or digitally stored in any remote location. This proposed work gives better avalanche effect and strict avalanche effect on comparing with the original existing AES algorithm. Results of the proposed algorithm are obtained after testing 1000 pairs of samples of different secret key. And it shows that 58% of the times, new proposed algorithm have better avalanche effect than the existing algorithm.

改进的具有动态移位行，子字节和混合列操作的高级加密标准算法的一种新颖方法，用于安全通信

在这个数字信息时代，通过互联网传输的数据容易受到多种攻击。为了通过互联网保存我们的信息，有必要使用一些加密方法。先进的加密标准是一种强大的对称，非固定加密算法，可以保护互联网上传输的信息免遭盗版或攻击。在这篇研究文章中，提出了一种新的和高效的密钥相关AES算法，用于保护Internet上或以数字方式存储在任何远程位置的数据的安全。与原来的现有AES算法相比，本文提出的工作具有更好的雪崩效果和严格的雪崩效果。该算法的结果是在测试1000对不同密钥的样本后获得的。结果表明58％的时间
