Abstract:
1. An ad-hoc radio communication verification system, comprising: a section sending data for verification data generation from a first data send/receive device to a second send/receive device, wherein the two send/receive devices are mutually connected by an ad-hoc radio connection; in the first data send/receive device, a section generating verification data from the sent data for verification data generation produced using a first generation algorithm, for outputting the generated first verification data to a first verification data output section and for communicating said first verification data to said second data send/receive device; in the second data send/receive device, a section generating verification data from the received data for verification data generation produced using the first generation algorithm, for outputting the generated second verification data to a second verification data output section and for communicating said second verification data to said first send/receive device; and a section at each of said first and second send/receive devices for determining whether the verification data at the first and second verification data output sections matches mutually, wherein the first generation algorithm generates a plurality of verification data, wherein for each verification data, it is determined whether the verification data at the first and second verification data output sections match mutually; a section establishing a serial sequence of operators that are composed of two or more of operators arranged in series, wherein the operators relate to the same or different one-way functions; and a section letting an input to the serial sequence of operators be the data for verification data generation and outputs of two or more of operators selected from all operators composing the serial sequence of operators or corresponding values be the verification data respectively; and wherein said section determining for each verification data whether the verification data match mutually at the first and second verification data output sections comprises a section for comparing sequences of verification data.
