RESUMO

The proposal of a cryptographic system of public key that uses classical and quantum convolutional codes of unit-memory presented in this work, is based on the use of trapdoors functions which when applied to submatrices reduce the capacity of correction of errors of the code. This process gives us an increase in the degree of privacy of information being sent, because of two factors, namely: to establish good unit-memory codes is necessary to solve the knapsack problem, and the reduction of the capacity of correcting errors of codes provided by scrambling the columns of generating submatrices. We also present in this work, news quantum convolutional codes [(4, 1, 3)]
