This paper presents design, implementation, evaluation and comparison of security enhancements in data transmission for next generation encryption highlighting the possible weaknesses within the current AES encryption algorithm. An enhanced encryption method with AES algorithm is used here within TLS. Enhancement is done in AES by first using chaos and then modifying the S-box .The use of chaos sequence makes the key space infinite and the static S-box is made dynamic using cipher key. To increase the complexity of the system, AES is integrated in Round structure. The evaluation focuses on: Encryption- Decryption time, Throughput-speed and Avalanche effect. Results show that speed of around 2Mbps is achieved which is compatible with LTE networks. Also performance evaluation of traditional AES and enhanced AES do not show much deviation and hence enhanced version can be a good alternative. More attack resistance and complexity is achieved by integrating AES in a Round structure which gives non linearity to the system .The number of rounds in the enhanced system can be made variable as shown in the results and can be application specific to achieve the desired throughput and speed making the system more compatible current and next generation networks.
