PUBLIC ENCRYPTION METHOD BASED ON USER ID |
摘要 |
A public encryption method based on user ID includes: setting, by a key generation server, at least one public parameter and master key used for generating a private key; receiving, by the key generation server, an inherent ID of a user from a receiving terminal, generating a private key based on the public parameter, the master key and the ID, and transmitting the generated private key to the receiving terminal; receiving, by a transmitting terminal, the public parameter and the ID from the key generation server, encrypting a message to generate a ciphertext, and transmitting the generated ciphertext to the receiving terminal; and receiving, by the receiving terminal, the ciphertext and the private key, and decrypting the ciphertext based on the received private key to obtain a message. |
