Asymptotic and algorithmic properties of sparse backpack cryptosystems, providing the packing density outside the interval (0,1), are determined in terms of basis of finite-order recurrent sequences. Design of such cryptosystems is used to construct a block cipher in blocks engagement mode. Results of analysis of speed and statistical properties of the encryption algorithm as compared to the known standards of block cipher are presented.
