Internal Structure of Rockey The core of Rockey is a 8-pins CPU with low-pressure design, the lowest working pressure is 2.2V. The main calculation of the key is done by it. Additionally, inside the Rockey, there is a memory Block (Rockey chip), which prevents the loss of saved data from power cut. According to different functions, we divide it into user zone, module zone and algorithm zoneˇ User can save important software information (such as serial number) in the Rockey, please note that each memory unit can write 100 thousands times, read time is not limited. 100 thousands is enormous, generally it can satisfy most users requirements except using it as a core memory. The special chip is built-in random number builder, seed code builder, user-defined algorithm interpreter, etc. Rockey supports IEEE1284 standard, ECP/EPP/SPP and other parallel port standard. The communication between computer and Rockey is through a special agreement; it not only has high anti-jamming ability for printing, but also has encryption and random number generator, this cause emulator no effect. Rockey can work with all kinds printer; scanner and other parallel port devices simultaneously, even can work with windows direct cable connection. Rockey can cascade with other dongle unlimitedly. However, because the Rockey itself has no power supply and utilizes computer parallel port power, so cascading numbers will be limited by parallel port pressure. Generally speaking, computer parallel port pressure is 3-5V, the lowest working pressure of Rockey is 2.2V. But if printer is connected behind the Rockey, and it is shutdown, then parallel port pressure maybe reduce to 2V(some printer). In this condition, Rockey possibly cannot work normally. One new feature of Rockey is that it allows cascading between same password Rockeys, and it is ensure that all Rockeys can be searched. This is convenient for those multi-module encryption users. |
