This is a paper on Elliptic Curve Cryptography (ECC), which is a public-key cryptosystem for encoding data and forwarding over unsecure networks. The technical description and benefits of ECC are stated and contrasted with other cryptosystems. This is then followed by a proposal for a new image cryptosystem, which is based on the binary value of pixels and grouping bits. A simple application is executed to show how the ECC can be used to convert, group, map and encrypt an image. Finally, an analysis is carried out to ascertain the strength of the encrypted image to withstand statistical and brute force attacks.
