Developing an Effective and Compressed Hybrid Signcryption Technique Utilizing Huffman Text Coding Procedure

Abstract

The functions of digital signature and public key encryption are simultaneously fulfilled by signcryption, which is a cryptographic primitive. To securely communicate very large messages, the cryptographic primitive called signcryption efficiently implements the same and while most of the public key based systems are suitable for small messages, hybrid encryption (KEM-DEM) provides a competent and practical way. In this paper, we develop a compressed hybrid signcryption technique. The hybrid signcryption is based on the KEM and DEM technique. The KEM algorithm utilizes the KDF technique to encapsulate the symmetric key. The DEM algorithm utilizes the AES algorithm to encrypt the original message. Finally the signcrypted data is compressed with the help of Huffman text coding procedure. Here, for the security purpose, we introduce the three games and we proved the attackers fail to find the security attributes of our proposed signcryption algorithm.
