A method of transmitting K messages using divided message authentication codes (MACs) in a controller area network (CAN) includes: generating a MAC using a first message and a specific MAC, performing a first operation with respect to j using j-th messages subsequent to the first message and a second MAC part of the generated MAC, performing a second operation with respect to j using a result of the performed first operation and a j-th subblock subsequent to a first MAC subblock among K MAC subblocks obtained by dividing a first MAC part of the generated MAC, transmitting the first message along with the first MAC subblock, and transmitting K-1 j-th messages in an order of j, each of the j-th messages being transmitted along with a j-th result of the performed second operation.

A method and apparatus for authenticating packets in a controller area network (CAN) are disclosed. The method includes transmitting messages using a mixture of message authentication codes (MACs) in a controller area network (CAN). In addition, a first MAC is generated using a first message and the first MAC is divided into a first MAC part and a second MAC part. A second MAC is generated using a second message and the second MAC is divided into a third MAC part and a fourth MAC part. A linear operation is performed between the second MAC part and the third MAC part to generate a first authentication MAC. The first message is transmitted with the first MAC part and the second message is transmitted with the first authentication MAC.

The present invention relates to a photobioreactor for microalgae cultivation having a bubble circulation structure, which allows gas flowing into a cultivation space to generate a vortex and thus circulate microalgae, thereby improving cultivation efficiency of the microalgae. A photobioreactor for microalgae cultivation according to an embodiment of the present invention includes a cultivation panel major body having the cultivation space into which the microalgae are injected to be cultivated; a gas supply pipe provided at a lower portion of the cultivation panel major body to pass through the cultivation space in a transverse direction and thus discharge inflow gas; and at least one vortex forming partition extending in a transverse direction from an internal wall of the cultivation panel major body and formed to have an arc shape and thus cause a vortex to an ascending current of gas supplied through the gas supply pipe.
