Integrity (I) codes: Message Integrity Protection and Authentication over Insecure Channels

Jean-Pierre Hubaux, Mario Cagalj, Srdan Capkun

Inspired by unidirectional error detecting codes that are used in situations where only one kind of bit errors are possible (e.g., it is possible to change a bit “0” into a bit “1”, but not the contrary), we propose integrity codes (I-codes) for a radio co ...
