Hybrid PKDS in 4G using secured DCC

In this paper, a modified security scheme based on RSA, Symmetric key Cryptography, Random number generators and Se4GE system. This system provides security in various accesses of LTE and LTE-A networks and improvises existing system by providing end-to-end security between UE and MME and focuses on Key Management Process. The proposed scheme generates all required keys to support Intelligent Protection-Key chain mechanism and ensures security of DCC. Multiple approaches like Random Number Generators, HMAC, Logical operations for encryption and decryption, makes these security levels more advance and efficient. DCC mechanism is used during the first authentication message in order to achieve highly secured mutual authentication between two entities of network. Security and performance analysis shows that proposed algorithm has better performance and security than the existing algorithm.
