Research And Hardware Implementation Of Cryptosystem Based On The AES And ECC

Security issues are playing an important role in computer networks. As the Internetbecomes more and more accessible to the public, many kinds of commercial and socialtransactions can be performed electronically through the network, various cryptographicalgorithms are needed in order to insure the security of these activities. In addition, nowthe implementation of cryptographic algorithm is on the transition from software tohardware and the cryptoproduct is paid more and more attention. Therefore, it is veryimportant to study and analyze the popular cryptographic algorithm and it is hardwareimplementation for the sake of nation’s information security.The present data encryption systems are analyzed in the dissertation to propose themixed cryptosystem based on the AES (Advanced Encryption Standard) and ECC(Elliptic Curve Cryptography), which will actualize encryption of data, digital signatureand identification with high efficiency in Internet communication, and solve theproblem of antinomy of speed and security in cryptosystem. First, this dissertationresearches and analyzes on the thought, the method and ecology and field of applicationof many kinds of data encryption technology show the mathematical description tosymmetry cryptogram and public key cryptogram and its characteristics based on brieflyon the current situation of the in formation security and the basic notion as well asmathematical model of data encryption technology; Secondly, the mixed cryptosystembased on AES and ECC is build forward in according with the characteristic of theencryption method of the data the detailed discussion is hold on two mathematicalprinciples, algorithm realization safe performance, etc. At the same time its work flow isalso given; thirdly, AES and ECC encryption algorithm for hardware implementation ofthe design to make a detailed analysis, using high-speed DSP chip TMS320C6713platform, popular USB2.0interface chip EZ-USB FX2CY7C68013to communicatewith the host. Focuses on the design of various parts of the platform, gives the designresults; finally, the plan which is applied to the secure communication service system ofa research institute is elaborated. The advantages of the ECC cryptosystem such asshort-key, low expenses, low request of the band, the quick speed of calculation and thehigh superiority of AES algorithm effectively solute the problem of the confidentiality,the personal identification, the integrity and the Non-repudiation of information.
