Abstract: A method and system for securely transferring a multiplicity of short messages using an unsecure connection begins by loading a secure domain component on a client device using a secure connection and then loading an unsecure domain component on the client device. Encrypted messages are sent from an unsecure server to the unsecure domain component. The client device transfers the received encrypted message from the unsecure domain to the secure domain, where the secure domain component decrypts the received encrypted messages. This method works repeatedly without reloading either the secure domain component or the unsecure domain component and by using the unsecure connection to transfer the encrypted messages.

Abstract: Message formats and apparatus are described that reserve access to a communication medium in a multicast system. A first message, a multicast request-to-send message, includes a duration field having information representing the reserved time for a communication medium, multicast receiver and transmitter address fields, and bits that specifies a destination that is expected to reply to the multicast digital message. The bits that specify a destination can be extended to a plurality of fields that each contain different destination identifiers. Example destination identifiers include association identifiers or media access control addresses. Alternately, the bits that specify a destination can have a first field containing an offset and a second field indicating destinations with respect to the offset. A second message includes a duration field and multicast receiver and transmitter address fields. The second message is used to cancel a data transmission resulting from a multicast request-to-send message.

Abstract: The invention provides a method for a web browser based remote administration system to maintain its security by utilizing an ActiveX control or a plug-in, without relying on HTTPS protection to transact management information. The invention does not burden the embedded system and thus is ideally suited for the remote administration of embedded systems. The invention provides a method to calculate a security code base upon identical algorithms in the administrative system having the browser and the embedded system. When the browser-based administrator submits the management information, an operator packages the control information as a string and invokes the security function in the plug-in with the string as a parameter. After the security function returns the result, the operator sends the form data together with a coded digest to the remote system. The digest may be embedded in the form data, for example, as a hidden field.
