| 摘 要： | 3D密码是CANS 2008提出的新的分组密码算法，与以往的分组密码算法不同，该密码采用3维结构。该文根据3D密码的结构特性，得到了3D密码的5.25轮和6.25轮新的Square区分器，重新评估了其抗Square攻击的强度。攻击结果表明:新区分器对6轮3D密码攻击的数据复杂度和时间复杂度比已有的结果好，并且还可应用到7轮，8轮和9轮的3D密码攻击中。

| Abstract: | 3D cipher is a new block cipher proposed in CANS 2008. It is different from all known block cipher as it uses the three dimension structure. According to the structure properties of 3D cipher, a new 5.25-round and a new 6.25-round square distinguishers are presented, and the square attacks on reduced- round 3D are improved. Attacking results demonstrate that 6-round attack is better than the known square attacks in data complexity and time complexity. Moreover, these two new distinguishers can be applied to 7/8/9-round 3D cipher. |
