Can the UDPi security solution protect data in standard external devices?
UDPi can protect data in all external devices. External devices included in these terms are EPROM, FLASH, RAM, SRAM, and DRAM among other standard devices to store data. Some current protection companies offer data protection in an external device in a serial manner. Only a few lines of data exchange are allowed in such applications and the processor must send a key. This in turn challenges the data storage device and the device is able to read the data. There are problems with this method, however, because data is not protected under this regime once it is transmitted to the main processor. Additionally, devices that offer such protection can be quite costly. UDPi protects data in external devices with cost efficiency in mind. Applying the same fundamental principles with UDPi can protect data from a small 4-bit microcontroller up to the most powerful processor available on the market.
