Abstract：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 se-cure communication between wireless printers and other mobile devices,and has broad application prospects.
