摘要
为解决物理公章管理中的安全隐患(如违法滥用、盗用和仿刻等问题),提出一种基于无线打印机的双信道随机数交叉认证算法(DCRCA)。算法结合蓝牙与Wi-Fi信道的协同工作,改进AES加密算法,提升数据加密过程中密钥的随机性与动态性。提出一次一密算法,做到用印事后可追溯,结合数据完整性校验算法及数字水印技术,加强公章图案数据在传输中的安全性,有效防止中间人攻击、重放攻击和数据篡改等安全威胁。实验结果表明,算法在提升安全性的同时,保持了高效性和低延迟,能够有效支持高安全需求场景(如加密文件和公章打印)。为无线打印机及其他移动设备间的安全通信提供了新的思路,具有广泛的应用前景。
To address security risks in physical seal management,such as illegal misuse,theft,and forgery,a Dual-Channel Randomized Cross Authentication Algorithm(DCRCA)algorithm based on a wireless printer was proposed in this paper.The algorithm combines the collaborative work of Bluetooth and Wi Fi information channels,while improving the AES encryption algorithm to enhance the randomness and dynamism of the key during data encryption.The one-time encryption algorithm has been applied,which can achieve traceability after printing.Combined with data integrity verification algorithms and digital watermarking technology,it strengthens the security of official seal pattern data during transmission,effectively preventing security threats such as man in the middle attacks,replay attacks,and data tampering.The experimental results show that the algorithm maintains high efficiency and low latency while improving security,and can effectively support high security scenarios such as encrypted files and official seal printing.This technology provides new ideas for secure communication between wireless printers and other mobile devices,and has broad application prospects.
