Abstract
Embodiments of the invention relate to efficient methods for authenticated communication. In one embodiment, a first computing device can generate an ephemeral key pair comprising an ephemeral public key and an ephemeral private key. The first computing device can generate a first shared secret using the ephemeral private key and a static second device public key. The first computing device can encrypt request data using the first shared secret to obtain encrypted request data. The first computing device can send a request message including the encrypted request data and the ephemeral public key to a server computer. Upon receiving a response message from the server computer, the first computing device can determine a second shared secret using the ephemeral private key and the blinded static second device public key. The first computing device can then decrypt the encrypted response data from the response message to obtain response data.
