SYSTEM AND METHOD FOR DIFFERENTIAL ENCRYPTION

摘要

Some embodiments include a Trusted Security Module that creates secure connections using a set of split keys. Some embodiments include the creation of remote and local keys that are distributed to multiple devices. When the devices wish to communicate with each other, the remote and local keys are combined into connection keys to encrypt and decrypt messages. The remote and local keys may be combined in a variety of ways, including appending the remote key to the local key. A key mask may be used to create a connection key by using various combinations of bits from the remote key and from the local key. Other embodiments are described.

主权项

1. A method for differential encryption comprising:
supplying a first set of remote and local keys to a first associated device and a second associated device; coupling the first associated device to the second associated device; exchanging encrypted identification messages between the first associated device and the second associated device; determining the remote and local keys to be used for secure communication between the first associated device and the second associated device; and combining the remaining remote and local keys to form a connection key for secure communication between the first associated device and the second associated device.
