BOOTSTRAP CHANNEL SECURITY ARRANGEMENT FOR COMMUNICATION NETWORK |
摘要 |
Apparatus and a method are disclosed to enable online modification and upgrading of terminal software in a communication network while maintaining the integrity of communication between a service provider and a subscriber using the network. Software is downloaded on a booter channel on the communication network. A subscriber terminal, coupled to the network initiates a communication with the network to receive downloaded booter data. The downloaded data is stored, and a checksum is computed from at least a portion of the downloaded data. The checksum is tested for validity, and control of the subscriber terminal is released to the downloaded software only if the checksum is valid. |
