Briefly describe the security risks and solutions of e-commerce?

E-commerce is a trade conducted on the open Internet, and a large amount of commercial information is stored and transmitted on computers and networks, thus forming the risk of information transmission. Therefore, these measures can be realized by using data encryption (including key encryption and public key encryption), while digital envelope technology is realized by combining key encryption and public key encryption technology.

2. Security risks of data integrity.

Data integrity security risks refer to data being tampered with during transmission. Therefore, using secure hash function and digital signature technology can achieve measures to ensure that data is not tampered with. Double digital signature can be used to ensure the integrity of data in multi-party communication.

3. Security risks of certification.

In online communication, the two parties don't meet each other. When trading or exchanging sensitive information, it is a security risk of identity verification to confirm the true identity of the other party and whether the account information of the other party is true. The solution can be realized by password technology, public key technology or digital signature technology and digital certificate technology.

4. The security risk of transaction rejection.

When both parties in online transaction transmit data, when the transaction occurs, both parties do not realize the denial security risk brought by their true will expression. The measure is that the transaction must have its own unique information that cannot be copied by others, so as to ensure that there is evidence to be found when there is a dispute in the transaction, which can be realized by digital signature technology and digital certificate technology.
