The invention relates to the technical field of
data transmission, and particularly discloses a
data transmission security
protection system adapted to a communication
base station, which comprises a sending end, a communication
base station, a receiving end and a block chain
verification unit, the sending end is in communication connection with the receiving end through a network transmission interface of the communication
base station, and the sending end and the receiving end are both connected with the block chain
verification unit. Through cooperative operation of a sending end, a communication base
station, a receiving end and a block chain
verification unit, in terms of
data integrity verification, a
dual mechanism combining a
message authentication code technology and a
digital signature is adopted, the
message authentication code technology can quickly check whether data is tampered or not, the
digital signature ensures that a
data source is real and non-repudiation, and common tampering attacks are effectively resisted; and meanwhile, a block chain distributed account book technology is introduced,
safe storage and reliable verification are provided for important
data transmission records by utilizing decentralization and tamper-resistant characteristics of the block chain distributed account book technology, and even if data are tampered, the tampered data can be timely perceived through an original hash value, so that the
data integrity protection capability is greatly improved.
