Tactical Information Communication Network(TICN) uses both a wireless and wired network. To support mobility in battlefield environments, the application of Ad-hoc networking technology to its wireless communication has been examined. However, Ad-hoc network is faced to many security threats due to its intrinsic characteristics. Therefore, to apply the Ad-hoc networking technology to battlefield environments and TICN, an intensive study on security countermeasure must go side by side with the development of enabling technology. In this paper, we suggest an efficient key management scheme for TICN of which the Ad-hoc networking technology is applied.

This paper is a fundamental study on the mechanical properties of the high performance concrete confined with metal lath laterally. According to the results, the compressive strength and flexural strength increases with increase of metal lath thickness due to enhancing confined force. The brittle failure is caused at maximum load in plain concrete. But, in case of concrete confined with metal lath laterally, strain stress increases a little. In flexural load curve, energy absorbtion increases with increase of metal lath thickness, so it resists continuous load, deflection and crack is retained. Length change ratio decreases with increase of metal lath thickness due to confined force.
