Container security
First Claim
1. A container security system, comprising:
- a container security device, comprising;
a housing;
electronic circuitry; and
cabling;
wherein the electronic circuitry is disposed within the housing, and include first and second microprocessor functions and an interface for accepting and providing data;
wherein the cabling is removably coupled to the housing, provides the only communicative coupling between the first microprocessor function and the second microprocessor function, and is adapted to be attached to a container latch so as to break the communicative coupling if the latch is opened;
wherein the housing includes a port for the electronic circuitry interface;
wherein the electronic circuitry is adapted to receive an event credential, a cryptographic key, and initial plaintext data via the electronic circuitry interface;
wherein the electronic circuitry is adapted to store the event credential, the cryptographic key, and the initial plaintext data for access by the first microprocessor function such that the second microprocessor function does not have access to the event credential, the cryptographic key, and the initial plaintext data; and
wherein the first microprocessor function is adapted to encrypt the initial plaintext data using the cryptographic key according to the event credential to produce encrypted data;
the container security system further comprising at least one portable computing device that is adapted to decrypt the encrypted data using the cryptographic key according to the event credential, to provide unlock plaintext data.

Abstract
A container security device includes a housing, electronic circuitry, and cabling. The electronic circuitry is disposed within the housing, and includes first and second microprocessor functions and an interface for accepting and providing data. The cabling is removably coupled to the housing, provides the only communicative coupling between the first microprocessor function and the second microprocessor function, and is adapted to be attached to a container latch so as to break the communicative coupling if the latch is opened. The housing includes a port for the electronic circuitry interface. A method of providing container security includes closing a container using a latch device and removably coupling the cabling to the housing so that the communicative coupling is broken if the latch is opened., providing the only communicative coupling between the first microprocessor function and the second microprocessor function.
