Abstract
Methods and systems for securely communicating with an access control system are provided. The methods and systems establish, between first and second devices, a communication session based on a plurality of ephemeral keys. The methods and systems compute, by the first device, a shared session key as a function of a second public key of the second device and a sum of a first private key of the first device and a first ephemeral key of the plurality of ephemeral keys; and compute, by the second device, the shared session key as a function of a second private key of the second device and a sum of a first public key of the first device and a second ephemeral key of the plurality of ephemeral keys. The methods and systems exchange one or more messages securely between the first device and the second device using the shared session key.
