This paper proposes a new approach to encrypt data with new modified cryptosystem based on elliptic curve. This new version utilizes the original Menezes Vanstone cryptosystem. But it has some additional features to cryptosystem's encryption method. According to the encryption method, first the message is divided into blocks that contain only one character, and then each character is converted to hexadecimal value. A hexadecimal value of each character has two digits. These two digits allow us to express the message as a point in curve. The knowledge of each character's point need not be sent to the recipient. The paper explains the implementation of encrypting data with new modified cryptosystem based on elliptic curve using VHDL.
