| Summary: | I-PRESENT was a lightweight SPN block cipher for resource-constraint environments such as RFID tags and sensor networks.The biclique structures of I-PRESENT with sieve-in-the-middle technique was an constracted.The biclique cryptanalysis schemes on full-round I-PRESENT-80 and I-PRESENT-128 were proposed for the first time.The results show that the data complexity of the biclique cryptanalysis on I-PRESENT-80 and I-PRESENT-128 is 2 <sup>26</sup> and 2<sup>36</sup> chosen ciphertexts respectively，and the time complexity on them is 2 <sup>79.48</sup> and 2 <sup>127.33</sup> encryptions respectively.The time and data complexity are better than that of the exhaustive attack.In addition,the time complexity on them can be reduced to 2 <sup>78.61</sup> and 2<sup>126.48</sup> encryptions by using related-key technology of I-PRESENT. |
