  • Method and system for establishing cryptographic communications between a remote device and a medical device
    Patent number: 8892886
    Abstract: A method and system establishing cryptographic communications between a remote device and a medical device, with the medical device having less processing power than the remote device are disclosed. The method may comprise establishing unencrypted communication between the remote device and the medical device, generating an asymmetric key pair by the remote device comprising a public key and a private key, generating a key request message and sending of the key request message together with the public key to the medical device, generating a pre-master key and encryption of the pre-master key with the received public key by the medical device, generating a key response message and sending of the key response message together with the encrypted pre-master key from the medical device to the remote device, decrypting the encrypted pre-master key with the private key by the remote device, and deriving a master key as a symmetric key from the pre-master key.
