Efficient S-repetition method for constructing an IND-CCA2 secure McEliece modification in the standard model

The paper is devoted to the construction of IND-CCA2-secure modification of the McEliece cryptosystem in the standard model. The modification uses S-repetition encryption of S/2 various messages with one common secret permutation, in contrast to other modifications that use S -repetition encryption of one message. Thus, this modification provides IND-CCA2-security with an efficient information transfer rate
