摘要

多媒体网络技术是指基于文本数据通信的多媒体网络教学,可以更好地利用高校体育教学中的体育资源。多媒体技术结合了计算机和视频技术。它是指将两个或两个以上的声音和图像组合在一起,形成一个可以传递信息的系统。当初始密钥发生轻微变化时,方案的哈希比特变化率大于0.451的阈值,说明本文的哈希算法具有良好的密钥敏感性。感知到的哈希值对密钥的变化越敏感,攻击者估计密钥的难度就越大,哈希密钥的安全性也就越好。因此,以上实验可以证明本文的哈希算法是安全的。本文提出的体育网络远程教育的出现为学校提供了更广阔的舞台,为提高全社会公民的整体身体素质做出了更大的贡献。

Practice of PE Teaching Reform in Colleges and Universities Under the Background of Multimedia Internet
Multimedia network technology refers to multimedia network teaching based on text data communication, which can make better use of sports resources in college physical education teaching. Multimedia technology combines computer and video technology. It refers to the combination of two or more sounds and images to form a system that can transmit information. When the initial key changes slightly, the hash bit change rate of the scheme is greater than the threshold value of 0.451, which shows that the hash algorithm in this paper has good key sensitivity. The more sensitive the perceived hash is to the change of the key, the more difficult it is for the attacker to estimate the key, and the better the security of the hash key. Therefore, the above experiments can prove that the hash algorithm in this paper is safe. The appearance of sports network distance education in this paper provides a broader stage for schools and makes greater contributions to the improvement of the overall physical quality of citizens in the whole society.
