论文摘要
哈希功能是密码学的重要分支。基于量子步行的哈希功能是一种新型的哈希功能，它是安全，灵活，高效且兼容的。所有现有的基于量子步行的哈希函数均由每个步骤中的一个位消息控制。在本文中，通过使用与时间依赖的受控量子步道在完整的图形上使用自动圈进行处理，以批量处理量处理消息。提出的哈希函数急剧加速了哈希处理，因此更高效率。
The hash function is an important branch of cryptology. Controlled quantum walk based hash function is a kind of novel hash function, which is safe, flexible, high-efficient, and compatible. All existing controlled quantum walk based hash functions are controlled by one bit message in each step. To process message in batch amounts, in this paper, controlled alternate quantum walk based block hash function is presented by using the time-position-dependent controlled quantum walks on complete graphs with self-loops. The presented hash function accelerate the hash processing dramatically, so it is more high-efficient.
