CSD is Active RFID based Container Security Device which is proposed by the U.S Department of Home Security. It is mounted inside the container to sense opening of the container door. ConTracer is the CSD which is developed in this research whose major features are sensing door opening status as well as history inquiring on internal environment and shock to the container by mounting the temperature/humidity/shock sensors. Moreover, its RFID frequency bandwidth uses 433MHz and 2.4GHz to correspond actively to the radio regulations used by different countries. This paper introduces the development trend of CSD, compares the ConTracer which is developed thru this research and other company's CSD, and introduces CSD System which is designed and established using ConTracer. Finally, the implemented CSD System is verified by applying the demonstration service to container distribution between Korea and China.

CSD(Container Security Device) is a security device with sensors that can detect the abnormal behavior such as illegal opening of a container door. Since the CSD provides security and safety of the container, CSD should not only provide security services such as confidentiality and integrity but also cloning detection. If we can not detect the cloned CSD, an adversary can use the cloned CSD for many illegal purposes. In this paper, we propose a policy based cloned CSD detection mechanism. To evaluate proposed clone detection mechanism, we have implemented the proposed scheme and evaluated the results.

A container security device (CSD) monitors intrusions through the cargo door; it is a reduced function device that uses IEEE 802.15.4 with a beacon mode. However, in the beacon mode, the CSD consumes too much battery power in periodical idle listening and sensing trials. Moreover, the CSD cannot send the message to the CSD reader actively, and it makes big latency problem. Therefore, we propose a low-power CSD to reduce the unnecessary power consumption. The proposed CSD follows the requirements of the U.S. Department of Homeland Security, and reduces battery consumption through a power-efficient hardware design, a night-watch mechanism for low-power operation and low-power sensing to reduce unnecessary monitoring. And the CSD sends alert message to the CSD reader. Simulation results show that our CSD reduces battery consumption by over 70% through the night-watch mechanism and by approximately 80% through the low-power sensing. And the CSD can send the alert message to the remote CSD reader by over 94%.

A Container Security Device (CSD) which is different existing RFID Tag strengthens the physical security as mounted inside the container and the information security as encrypts doubly a data. CSD must use the resources efficiently in order to operate with the battery. Therefore, it needs low-power mechanism which repeats the sleep period and channel scan period. However, by adjusting these periods, the trade-off occurs between energy efficiency and network connectivity. In this paper, we implement low-power CSD and resolve this problem by adjusting beacon period and channel scan time. As a result, We guarantee the network connectivity 95% or more and maximum life up to 16 days using common AA batteries.

In this paper, we describe application service development for secure land and marine transport based on CSD (Conveyance Security Device) systems. Based on CSD systems, we present application service and security service according to relevant standards as well as test procedure of developed services. Exploiting temperature, moisture, impact sensors, state monitoring function of container freight was developed to prevent disaster during transportation in addition to security function with CSD. For confidentiality of messages exchanged among application service entity and CSD systems, Encryption and decryption functions going by RC5 and AES-128 algorithms were implemented at desktop PC and 8 bit CPU environments, respectively. Measuring the elapsed time during encryption and decryption shows that two algorithms are allowable for the application service.

This paper is intended as performance verification of efficient container door Open/Closed detection mechanism for Container Security Device(ConTracer) to container cargo transportation. Container door Open/Closed detection mechanism using Reed sensor is important to satisfies the US Department of homeland security customs and border protections requirements to many types of container door. Also, Verify that the container door is configured correctly and that you can check the illegal opening. In this article, Performance valuation of this Contacer on reed sensor has been verified through field test for each other 30 containers. Once the improvement has been made, we are suggest that propose skills will meet the highest standards for container security safety.
