User terminal A and B have a key KA and KB, respectively. Data storage server has a replacement key KA→B. User terminal A generates an authenticator tag with data M and temporary key R, generated by user terminal A, and generates a key k with temporary key R and key KA. User terminal A transmits data M, key k, and authenticator tag to the data storage server. Data storage server generates a key k′ from key k and replacement key KA→B, and transmits data M, key k′, and the message authenticator tag to user terminal B. User terminal B generates temporary key R with key k′ and key KB and generates an authenticator tag′ to compare with the received authenticator tag."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Data processing system","description":"Provided is a data processing system in which data are uploaded from a user terminal A to data storage server, and data are accessed from a user terminal B.
