摘要:

I-PRESENT是一种适用于RFID、无线传感节点等资源受限环境的代换——置换型分组密码。利用中间筛选技术来构造I-PRESENT的biclique结构,首次对全轮I-PRESENT-80和I-PRESENT-128算法进行了biclique攻击。结果表明,biclique对I-PRESENT-80和I-PRESENT-128攻击的数据复杂度分别为226和236个选择密文;攻击的时间复杂度分别为279.48和2127.33次加密。攻击在时间复杂度和数据复杂度上均优于穷举。利用提出的I-PRESENT的密钥相关性技术,攻击的时间复杂度可以进一步降低到278.61和2126.48

Abstract:

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 26 and 236 chosen ciphertexts respectively,and the time complexity on them is 2 79.48 and 2 127.33 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 78.61 and 2126.48 encryptions by using related-key technology of I-PRESENT.

Key words: lightweight block cipher, PRESENT, matching-with-precomputations, biclique cryptanalysis
