The invention discloses a dual
encryption method based on MD5 and an asynchronous request, and relates to the technical field of
data security, and the method comprises the step of establishing a dynamic salt value generation model, an asynchronous request
processing model, a block chain storage
verification model, an edge calculation
encryption model and a dual inspection model. Through cross-domain
technology fusion advantages, biological characteristics are used as a part of a dynamic salt value, double
authentication of'behavior + physical characteristics' is realized, through an edge-cloud collaborative architecture
hybrid calculation mode, data
encryption processing efficiency is improved, hash security is enhanced through the dynamic salt value, efficiency and stability are improved through asynchronous transmission, and finally, the data encryption
processing efficiency is improved through the edge-cloud collaborative architecture
hybrid calculation mode. Through
collaborative design of a dynamic salt value, asynchronous transmission, a block chain, edge calculation and dual
verification, a multi-level and high-robustness data encryption
transmission system is constructed.
