The description of a new method of designing a public key cryptosystem using idempotent elements is given. This method is connected with the Merkle-Hellman method and is illustrated by three versions of the design that show the properties of the cryptosystem obtained and its advantages as compared to the cryptosystem of Merkle-Hellman.
