Modelling DES Soft-Cores for information protection

  • This paper discusses the possibilities of IPtechnologies for information protection. An analysis of modern information protection Soft-Cores which support symmetric block ciphers is given. Development perspectives of the Soft-Cores are described. The DES Algorithm and the variations of the architecture of the DES Soft-Core models are considered, their analysis provided and they are compared with some existing DES Soft-Cores on the world market. Two architectures - iterative and pipelined - are identified. Twenty six variations of the DES Soft-Core are proposed and a comparative analysis of their architecture is given. The proposed DES Soft-Cores support all of the discussed functional possibilities. Thus a high performance is achieved, the equipment volume for their realization is lowered and they can be used effectively in a wide spectrum of the application fields.
