摘要
A system based on layered, two-tier double cryptographic keys providing a closed cryptosystem within a secured network environment, the system including a digital key management device and a network node. The digital key management device generates a first-tier cryptographic key, a second-tier cryptographic key and makes the first-tier and second-tier cryptographic keys publicly accessible within a first and a second secured walled regions that are accessible to a network node registered to a first authentication database associated with an access server of the system, encrypts a first and second content with the first-tier and second-tier cryptographic keys, and generates encrypted first and second content. The network node requests access to the first secured walled region, accesses the first-tier and the second-tier cryptographic keys, decrypts the first and second content, generates first and second data containers based on the decrypted content, and transfers the data containers to a client device.
