This paper presents a study on various types of attacks on the security of a robotic system. The work focuses on hardware attacks, and particularly considers vulnerable features of the I2C protocol. An analysis of the effects of these attacks, when they are applied on a differential driving mobile robot that aims to track a path, is presented.

I2C is a serial communication protocol, so data is transferred bit by bit along a single wire the SDA line. Like SPI, I2C is synchronous, so the output of bits is synchronized to the sampling of bits by a clock signal shared between the master and the slave. The clock signal is always controlled by the master. The master sends the address of the slave it wants to communicate with to every slave connected to it. Each slave then compares the address sent from the master to its own address.

Hardware Attacks on Mobile Robots: I2C Clock Attacking

This article covers the essential characteristics and prominent advantages of the inter—integrated circuit AKA I2C serial-communications protocol. It should come as no surprise that a common feature of electronic systems is the need to share information among two or three or ten separate components. Each protocol has its pros and cons, and it is important to know a little about each one so that you can make an informed decision when choosing components or interfaces. This article is about I 2 C, which is typically used for communications between individual integrated circuits located on the same PCB. You need to know the basic characteristics of I 2 C before you can thoroughly understand a comparison between these three interfaces, so we will discuss that topic at the end of this article.

Nowadays the protocols play an essential role in the embedded system design. Without going to the protocols, if you want to expand the peripheral features of the microcontroller, the complexity and power consumption will increase. Transmitting and receiving the information between two or more than two devices require a communication path called as a bus system. A I2C bus is a bidirectional two-wired serial bus which is used to transport the data between integrated circuits. It was first introduced by the Philips semiconductors in The I2C bus consists of three data transfer speeds such as standard, fast-mode and high-speed-mode.

Introduction to the I2C Bus

It was invented by Philips and now it is used by almost all major IC manufacturers. I2C bus is popular because it is simple to use, there can be more than one master, only upper bus speed is defined and only two wires with pull-up resistors are needed to connect almost unlimited number of I2C devices. Each slave device has a unique address. Transfer from and to master device is serial and it is split into 8-bit packets. All these simple requirements make it very simple to implement I2C interface even with cheap microcontrollers that have no special I2C hardware controller.

another device is using the bus. Push-pull interfaces do not allow for this type of freedom, which is a benefit of I2C. Figure 2. Basic Internal Structure of SDA/SCL.

I 2 C Inter-Integrated Circuit , pronounced I-squared-C , is a synchronous , multi-master, multi-slave , packet switched , single-ended , serial communication bus invented in by Philips Semiconductor now NXP Semiconductors. It is widely used for attaching lower-speed peripheral ICs to processors and microcontrollers in short-distance, intra-board communication. Since October 10, , no licensing fees are required to implement the I 2 C protocol. One purpose of SMBus is to promote robustness and interoperability.

Лицо ее побелело, глаза не отрываясь смотрели на застывший кадр, демонстрировавший неподвижное тело Дэвида Беккера, залитое кровью, брошенное на пол мини-автобуса. - Вы его убили! - крикнула.  - Вы его убили! - Она бросилась к экрану, протянула к нему руки.  - Дэвид… Все пришли в смятение. Сьюзан шла вперед, повторяя это имя, ее глаза неотрывно смотрели на экран.

 С вами все в порядке? - спросила девушка, заметив, что он переменился в лице. Беккер не мог оторвать глаз от ее руки. У него кружилась голова. Слова, которые он прочитал, были теми же, что произнес немец: ПРОВАЛИВАЙ И УМРИ. Девушка, заметно смутившись, посмотрела на свою руку.

Он выкинул его автобиографию в мусорную корзину, даже не прочитав. Нуматака в очередной раз посмотрел на часы. Американец по кличке Северная Дакота должен был бы уже позвонить. Нуматака начал слегка нервничать. Он очень надеялся, что ничего не сорвалось. Если ключ так хорош, как о нем говорят, он взломает самый совершенный продукт компьютерной эры - абсолютно стойкий алгоритм цифрового кодирования. Нуматака введет этот алгоритм в чипы VSLI со специальным покрытием и выбросит их на массовый рынок, где их будут покупать производители компьютеров, правительства, промышленные компания.
