Time-sensitive mobile commerce is vulnerable to message authentication delays. Significant power consumption incurred by cryptography is another limiting factor of most mobile devices. In this paper, we present a scalable mobile cryptosystem, which installs a group key and an elliptic curve private/public key pair in each device to enable both symmetric key and public key cryptography. Scalable key establishment protocols and secure routing protocols with scalable authentication are proposed to make tradeoffs between security and energy, according to different mobile applications.
