Beidou Short Message Communication Encryption Scheme with Improved SM4 Algorithm
Xinyi He, He Lei · 2023
Beidou short message function is widely used in all walks of life, and the security of its data transmission has become particularly important. Three-party hijacking, resulting in compromised data confidentiality and integrity. In response to this problem, this paper proposes a Beidou short message encryption scheme that optimizes the SM4 algorithm, which can solve the security problem of Beidou short message data transmission to a certain extent.
