Patent number: 9787677Abstract: 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.Type: GrantFiled: February 26, 2015Date of Patent: October 10, 2017Assignees: Hyundai Motor Company, Kia Motors Corporation, SNU R&DB Foundation, Industry-Academic Cooperation Foundation, Chosun UniversityInventors: Ho Jin Jung, Chung Hi Lee, Ho Yoo, Byoung Wook Lee, Hyun Soo Ahn, Ho Youn Kim, Young Sik Moon, Jun Young Woo, Young Sik Kim, Kang Seok Lee, Jong Seon No
