One-way data conversion apparatus and device |
摘要 |
<p>The verifier apparatus 50 includes a random number generation unit 51 that generates a 2n-bit random number, a separator unit 52 that separates the random number into two sets of n-bit data, a data conversion module 53 that converts one set of separated data using the other set of separated data as a key, and a comparator unit 54 that judges whether the converted result matches claimant data sent back from the claimant apparatus 60. The claimant apparatus 60 includes a separator unit 61 and a data conversion module 62 that have the same functions as the separator unit 52 and the data conversion module 53 in the verifier apparatus 50. The claimant apparatus 60 generates n-bit claimant data from the 2n-bit random number generated by the verifier apparatus 50, and sends the generated claimant data to the verifier apparatus 50.</p> |
