With the inclusion of IP stacks in mobile computers and devices, mobility support for Internet devices is becoming more important which allows mobile devices to move from one network to another while maintaining reachability via their permanent/home IP address. In IPv6, IPsec is implemented to only secure the signaling with high complexity, while user data is unsecured. In this paper, a new security mechanism for data integrity is proposed to overcome the unprotected data obstacle in route optimization of Mobile IPv6. In addition, it provides data security and protected communication among Mobile Node (MN) and Correspondent Node (CN). This algorithm detects and prevents an attacker who intends to modify the data by using a suitable existing encryption algorithm. When an attack is detected by MN or CN, the encryption will be started, not before attack detection. It is friendlier to delay sensitive application, including real-time services like networking game, interactive multimedia, video/audio streaming, as well as other services for data transmission which require low latency. In addition, enhanced security and handover schemes are applied to secure micro-mobility movement and reduce the handover delay and packet loss
