عنوان مقاله [English]
In this article, a hybrid encapsulation scheme based on polar codes is presented, in which the advantages and efficiency of asymmetric and symmetric encryption systems are combined with each other. The proposed hybrid encapsulation scheme includes two parts: a) key encapsulation based on polar codes whose task is to encapsulate, send and de-envelop the secret key required in the data encapsulation scheme based on polar codes, b. ) data encapsulation based on polar codes whose task is to encapsulate, send and deencapsulate data between authorized parties using the secret key exchanged by the key encapsulation scheme. The security analysis of the proposed hybrid encapsulation scheme has also been done by applying the comprehensive key search attack and the information set decoding attack. The results of the security analysis show that the proposed plan is safe against the intended attacks. The efficiency level of the proposed scheme has also been evaluated in terms of decryption failure rate and key length. The results of the analysis also indicate the suitability of the decoding failure rate and the short length of the key.
