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.
