Various mobile devices and applications are now used in daily life. These devices require high-speed data processing, low energy consumption, low communication latency, and secure data transmission, especially in 5G and 6G mobile networks. High-security cryptography guarantees that essential data can be transmitted securely; however, it increases energy consumption and reduces data processing speed. Therefore, this study proposes a low-energy data encryption (LEDE) algorithm based on the Advanced Encryption Standard (AES) for improving data transmission security and reducing the energy consumption of encryption in Internet-of-Things (IoT) devices. In the proposed LEDE algorithm, the system time parameter is employed to create a dynamic S-Box to replace the static S-Box of AES. Tests indicated that six-round LEDE encryption achieves the same security level as 10-round conventional AES encryption. This reduction in encryption time results in the LEDE algorithm having a 67.4% lower energy consumption and 43.9% shorter encryption time than conventional AES; thus, the proposed LEDE algorithm can improve the performance and the energy consumption of IoT edge devices.

Objective: To study the effect of Shengji Huayu Recipe (SHR)on the expression of MMP-3 and TIMP-1 in the skin ulcer tissue of diabetic rats., Methods: The skin ulcer model was established in diabetic mice. Different compatibility proportions of SHR [the ratio of Shengji Recipe (SJR) to Huayu Recipe (HYR) = 2:1, 1:1, and 1:2, respectively] were used to intervene. The expression of MMP-3 protein in the skin ulcer of diabetic rats was detected by Western blot method,and TIMP-1 protein was detected by immunohistochemical assay., Results: At each time point, there was no statistical difference in the blood glucose level among groups (P > 0.05). But all of them increased significantly,when compared with those of the normal wound group (P < 0.01). As for the difference between after would area treatment and before would area treatment, better effect was obtained in the SHR No. 3 group and the normal ulcer group than in the diabetic ulcer model group (P < 0.05). Results of Western blot showed that the MMP-3 protein expression was higher in the SHR No. 2 group than in the SHR No.3 group (P < 0.05). Immunohistochemical results showed that TIMP-1 protein expression was lower in the SHR No. 2 group than in the SHR No. 3 group and the diabetic ulcer model group (P < 0.05). TIMP-1 protein expression was higherin the SHR No. 3 group than in the SHR No. 2 group (P < 0.01)., Conclusion: Using SHR No.3 was conducive to the promotion of wound healing in early wound repair stage, and using SHR No. 2 might be conducive to inhibiting the formation of pathological scar.
