It is devised a new cryptosystem based on modified Reed Muller codes RM (r, m). The new cryptosystem is a modified version of sidel'nikov's one. This allows to increase the security of the public key, and to reconsider reed muller codes as good candidates for using in secure encryption scheme. An efficient decoding with the reed muller decoding algorithm RM (r, m) and an increased level of security against attacks of the sidel'nikov's cryptosystem due to minder and shokrolahi are the main advantages of the modified version.
