Abstract :
The cryptanalysis of a recently proposed public-key cipher is presented. The mathematical structure of the cipher is based on linear complementary subspaces over a finite field. The cipher is broken simply by multiplying the ciphertext by a matrix which is the multiplicative inverse of a matrix formed with the public information available
