基于Merkle树的移动平台文件完整性校验

移动平台的下载业务是除消息类业务外另一类重要的移动增值数据服务,对下载过程的有效管理和控制是该业务稳定运营的前提。下载数据的完整性是下载业务的核心内容。描述了移动平台下载业务内容完整性校验方案。提出了Merkle树在移动平台内容完整性校验上的实现策略,该策略通过缩短校验值在网络传输中的大小,来有效减少完整性校验的代价。理论分析与工程项目证明,该机制具有较高的安全连通性和较低的网络延迟。

File Integrity Check on Mobile Platform Based on Merkle Tree

In addition to the message service, the download service is another important business. The effective management and control of the download process is a prerequisite for stable operations for the business. The data integrity is the core content for download business. This article describes the content integrity check program in the download process of a mobile platform. It proposes a content integrity check strategy on the mobile platform based on Merkle tree, which reduces the cost of the integrity check effectively by shortening the size of checksum on the course of the network transmission. Theoretical analysis and the project has proven that the mechanism has high security connectivity and low network latency.
