The transmitter generates a truncated MAC code by selecting predetermined bits from a message authentication code (MAC) computed over a concatenation of a part of the message with a part of a previously transmitted message. The transmitter appends the truncated MAC code to the message for transmission. The receiver receives a previously transmitted message, the currently transmitted message, and the truncated MAC code, and generates an expected truncated MAC code by selecting predetermined bits from a message authentication code (MAC) computed over a concatenation of the part of the message with the previously transmitted message. The receiver authenticates the message and the previously transmitted message if the truncated MAC code as received is identical to the expected truncated MAC code."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Methods and devices for providing message authentication code suitable for short messages","description":"This application relates to devices and methods of authenticating messages exchanged over a network between a transmitter and a receiver.
