Design and Implementation of Telemedicine Client-Server Model Using Encryption and Decryption Algorithm in Single Core and Multicore Architecture on L

Project Report from the year 2011 in the subject Computer Science - Applied, Coventry University (M.S. Ramaiah School of Advanced Studies), course: M. Sc. [Engg] in Real Time Embedded Systems, language: English, abstract: Multimedia applications have an increasing importance in many areas. There is a growing need to store and transmit high quality video for applications where common coding schemes do not yield enough quality. An example of this is Telemedicine system is best example of Applied Medical Informatics. Several physiologic data, Digital images and video can be transmitted more rapidly and easily than conventional images and videos. In telemedicine expert physicians in tertiary care centres can view a digital image, videos and advice local physicians on the best plan of care without having to move the patient many miles away. Telemedicine will be implemented using the TCP client-server model. The clientserver model was originally developed to allow more users to share access to database applications. The data must be secure, when the data is transmitted from server to client, security must ensure that data will not be damaged by attackers and protects against danger, loss, and criminals. Even if someone tries to hack the data content of file should not be revealed to the attacker. So it is necessary to encrypt the data before transmitting the file using encryption methods. The encryption method used in server and client model is XOR or AES (advanced encryption standard) or Rijndael algorithm which is used to encrypt and decrypt the x-ray images of patients, drug prescriptions. The Rijndael algorithm allows encrypt video at high quality while achieving great encryption. This property makes the Rijndael algorithm a good option for building a video encryption able to obtain better performance than other more general purpose algorithms such as XOR or AES algorithm. One of the main problems when working with the video sequence is the huge datasets that have to

Design and Implementation of Low-power Nano-scale Hardware Based Crypto-systems

As the technology advances day by day, there is an essential need for a secured data transmission for exchanging information from one user to the other. Generally , data transmission techniques are achieved via private/public data networks. The transmission of data through these networks is not secured. Therefore, some kind of safety is needed for information exchange which is accomplished by encrypting the transmitted data. In this research a novel method is used in which hardware implementations of private/secret key encryption standards such as Advanced Encryption Standard (AES), Triple Data Encryption Standard (TDES) and Data Encryption Standard (DES) are integrated in a single silicon die of group centric Secured Information Sharing. This improves confidentiality, integrity and accuracy of the transmitted data. Advanced Encryption Standard is specified by National Institute of Standards (NIST) in 2001 as the specifications for encryption in electronic communication. It is also known as symmetric key algorithm as the encryption and decryption both are formulated using this single standard key. From the family of ciphers NIST selected three members of Rijndael family, each with key length of 128, 192 and 256 bits for each 128 bit block size as AES. For every key length a fixed number of rounds in AES are processed. For 128, 192 and 256 bits, 10, 12 and 14 rounds are executed respectively. In this research, AES 128 bits has been designed and implemented. Triple Data Encryption Standard (TDES) is a cipher algorithm where original Data Encryption Algorithm (DEA) or DES is applied three times. When DES was originally developed, it was sufficient to withstand the attacks using computer power of that era. However, with the remarkable increase in computing power, this algorithm was not complex enough to withstand the brutal attacks. To overcome this problem, Triple DES was proposed to offer high level of security without proposing any novel cipher algorithm. In this research all these three algorithms are implemented in Verilog and TSMC 65nm technology node. Xilinx ISE and Icarus Verilog are used for simulation of AES and DES. Cadence RTL Compiler is used to synthesize the design with minimum area. Finally the Graphic Database System (GDS) II layout of all the crypto cores and Top Module have been generated using Cadence Encounter.
