HACKING DEVICES USING MICROPROCESSORS ABSTRACT Network security is a never ending battle between the system design engineers and the computer hackers. In an effort to keep the hackers out‚ engineers have developed an impressive array of encryption algorithms‚ authentication protocols and intrusion detection systems. The hackers have developed an equally impressive way of bypassing the security walls. However‚ both groups have continued to overlook one of the most vulnerable links in

1. Frequency Division Multiplexing Frequency Division Multiplexing is a technique that can be applied when bandwidth of the link is greater than combined bandwidth of signals to be transmitted. Frequency Division Multiplexing technique is the process of translating the frequency of individual channel into per-assigned frequency slots within the bandwidth of the transmission medium. Different carries frequencies are assigned to different users. We can use any modulation scheme to assign carrier

The TJX company did not have many security controls put in place to prevent something like this from happening. The company used Wired Equivalent Privacy encryption system to handle their client’s credit and debit card information. This system was very easy for any hacker to gain access to people’s information. It was completely out of date and did not encrypt anything within the company‚ which made it more vulnerable. They did not install firewall security correctly. TJX had purchased many other

Scalable and Secure Sharing of Personal Health Records in Cloud Computing using Attribute-based Encryption Abstract Personal health record (PHR) is an emerging patient-centric model of health information exchange‚ which is often outsourced to be stored at a third party‚ such as cloud providers. However‚ there have been wide privacy concerns as personal health information could be exposed to those third party servers and to unauthorized parties. To assure the patients’ control over access

encrypt a message‚ each block of n letters (considered as an n-component vector) is multiplied by an invertible n × n matrix‚ again modulus 26. To decrypt the message‚ each block is multiplied by the inverse of the matrix used for encryption. The matrix used for encryption is the cipher key‚ and it should be chosen randomly from the set of invertible n × n matrices (modulo 26). The cipher can‚ of course‚ be adapted to an alphabet

CheckPoint: TJX Companies The TJX Company was using the Wired Equivalent Privacy (WEP) encryption system‚ which caused the data theft at the TJX Companies. The WEP made it easy for hackers to navigate and steal information. TJX had out of date security and controls. TJX failed to properly encrypt data on many of the employee computers that were
