Abstract
Dynamic encryption for network communication includes distributing a key to a network entity and storing the key into the key table. A key in the key table is used to encrypt data, and an index of the used key in the key table is attached to the encrypted data. The encrypted data is sent to the network entity. Dynamic decryption for a network communication includes receiving a key from a network entity and storing the received key into a key table. Encrypted data is received from the network entity. A key in the key table is located based on an index attached to the data and the data is decrypted with the located key.
