Set of symmetric block ciphering Soft-Cores

The possibilities of IP-technologies for information protection are discussed. An analysis of modern information protection Soft-Cores that support symmetric block ciphers is done. Forty-six variations of the DES and Triple DES Soft-Core are proposed. The developed DES and Triple DES Soft-Cores support all of the discussed functional possibilities. This allows achieving a high performance, a low equipment volume for their realization and an effective usage of them at a wide spectrum of the application fields.
