As small, secure devices become more powerful and more wide spread, it has become desirable to support the dynamic provisioning and updating of multiple applications on such devices. This paper presents a simple mechanism for performing such provisioning and updating, even if the applications are mutually distrustful. The mechanism extends CLDC JavaTMtechnology with a classfile attribute that carries the certificates necessary to enable the added security.
