Title:
METHOD FOR TRANSMITTING KEY AND POS TERMINAL
Document Type and Number:
WIPO Patent Application WO/2019/178760
Kind Code:
A1
Abstract:
The present invention relates to the field of data security, and in particular to a method for transmitting a key and a POS terminal. In the present invention, a POS terminal acquires a first protection key corresponding to a sender. The POS terminal acquires a second protection key corresponding to a receiver. The POS terminal decrypts, according to the first protection key, a first work key ciphertext from the sender to obtain a work key plaintext. The POS terminal encrypts the work key plaintext according to the second protection key to obtain a second work key ciphertext. The POS terminal sends the second work key ciphertext to the receiver. The present invention boosts convenience in setting a protection key for secure transmission of a work key.
