In the paper developed a method for the implementation of the extended matrix operations cryptographic transformation of data. The structural scheme of the operations of the extended matrix of cryptographic transformation and synthesized a functional diagram of the module that implements these operations. The calculation of the number of operations. With this package of statistical tests performed NIST STS evaluation of operations over an extended matrix transformation for cryptographic protection of information.
