In this paper an efficient secured interleaver is utilized in Turbo codes for Long Term Evolution (LTE) system. The engine of the presented technique is the Baker formula; it works based on secret key. The proposed technique system improves the Bit Error Rate (BER) and the throughput as well as the security also. This scheme depends on chaotic Baker map encryption. A comparison study between the proposed chaotic interleaving scheme and the traditional block and convolutional interleaving schemes for LTE system transmission over an Additive White Gaussian Noise (AWGN) channel is presented. The simulation results show the superiority of the proposed scheme over the traditional schemes. It reveals also, the turbo codes perform better with the proposed technique compared to the internal block interleaver used in LTE system. The data ordering in the proposed scenario based on the determined key length, this key controls the power of data randomizing. It can be used as a secret key also, to enhance the LTE security, packet-by-packet protection
