The private key and a public key cooperatively constitute an a symmetric key pair. After receipt of a second private key portion of the private key, the client device generates a digital signature for transaction data using a current key which combines the second private key portion and a current key portion obtained by decrypting the reference first private key portion. A verification server verifies, based on the public key, whether a received digital signature is signed with the private key, and obtains the transaction data when verification result is affirmative."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Network authentication method for secure electronic transactions","description":"In a network authentication method, a client device stores a reference first private key portion obtained by encrypting a first private key portion of a private key.
