[Retracted] Optimization of AES-128 Encryption Algorithm for Security Layer in ZigBee Networking of Internet of Things

Table 1

AES encryption and decryption speed test.

Serial number	File size (MB)	Read time (ms)	Encryption time (ms)	Decryption time (ms)
1	0.5	129	38	86
2	1	204	43	87
3	4	386	58	127
4	10	478	126	181
5	24	937	281	374

The encryption and decryption test mainly uses 0.5 mb–24 mb data.
