发明名称 Roaming hardware paired encryption key generation
摘要 The roaming hardware paired encryption key generation coalesces a content variable with a network, or subnet, address to generate an encryption key. The source generates a content identification that is unique to the content being encryption and the network, or subnet, address is coalesced with the content indentification to generate a unique encryption key for the content being encrypted. The encrypted digital content is transmitted to the destination devices identified by the network, or subnet address, along with the content identification. At the destination, the destination devices regenerate the encryption by coalescing the content identification and the network, or subnet, address in the same manner as ciphertext is decrypted into plaintext.
