Abstract

A computer-implemented data transmission method and system are provided. A first transformed password (PWD) is acquired from the first node, wherein the first transformed PWD is derived from an original PWD. An encrypted message is acquired from the first node, the encrypted message being encrypted with a public key of the first node. A private key of the first node is recovered according to the first transformed PWD, the private key having been encrypted with the first transformed PWD and stored in the second node in advance. The encrypted message is decrypted with the recovered private key to obtain a decrypted message for processing.
