In recent decades, log system management has been widely studied for data security management. System abnormalities or illegal operations can be found in time by analyzing the log and provide evidence for intrusions. In order to ensure the integrity of the log in the current system, many researchers have designed it based on blockchain. However, the emerging blockchain is facing significant security challenges with the increment of quantum computers. An attacker equipped with a quantum computer can extract the user's private key from the public key to generate a forged signature, destroy the structure of the blockchain, and threaten the security of the log system. Thus, blind signature on the lattice in post-quantum blockchain brings new security features for log systems. In our paper, to address these, firstly, we propose a novel log system based on post-quantum blockchain that can resist quantum computing attacks. Secondly, we utilize a post-quantum blind signature on the lattice to ensure both security and blindness of log system, which makes the privacy of log information to a large extent. Lastly, we enhance the security level of lattice-based blind signature under the random oracle model, and the signature size grows slowly compared with others. We also implement our protocol and conduct an extensive analysis to prove the ideas. The results show that our scheme signature size edges up subtly compared with others with the improvement of security level.
