A device-to-device (D2D) communication method is provided. According to an inventive concept, the method comprises, storing, by a first device, first authentication data including a hash chain, which is a sequential concatenation of hash values, and storing, by a second device, second authentication data including an initial hash value of the hash chain, transmitting, by the first device, a final hash value of the hash chain to the second device, determining, by the second device, whether authentication between the first and second devices has succeeded by repeatedly hashing the initial hash value stored in the second device until a hash value identical to the final hash value is returned, and if a determination is made that authentication between the first and second devices has succeeded, performing, by the first and second devices, a connection establishment process for establishing a connection between the first and second devices.

The present invention relates to a composition comprising a bamboo plant extract for the prevention and treatment of inflammatory or blood circulation disease. The extracts of bamboo plant has potent anti-inflammatory activity by inhibiting NO production and blood circulation-improving activity by inhibiting elastase activity and healing the wound of vascular endothelial cell, activating u-PA expression and inhibiting PAI-1 expression, lowering cholesterol deposit and inhibiting neointima formation, therefore it can be used as a therapeutic or health care food for treating and preventing inflammatory or blood circulation diseases.
