Transmission of secure and authenticated data over a network

Abstract

A method, a system, and a computer program product for transmission of information over a network. A validity token is generated based on a received contactless card identifier associated with a contactless card. The validity token is generated upon validating the contactless card using the contactless card identifier, and transmitted to a first computing device. A second computing device is identified based on an information request received from the first computing device. The information request includes a first public key associated with the first computing device and the validity token. An encrypted response to the request and a second public key associated with the second computing device are sent to the first computing device. The second computing device generates the encrypted response and encrypts it using a shared key generated using the first public key. The first computing device decrypts the response upon generation of the shared key using the second public key.
