Ecsc-128 is a new stream cipher based on the intractability of the Elliptic curve discrete logarithm problem. The design of ECSC-l2g is divided into three important stages: Initialization Stage, Keystream Generation stage,
and the Encryption Stage. The design goal of ECSC-128 is to come up with a secure stream cipher for data encryption. Ecsc-l2g was designed based on some hard mathematical problems instead of using simple logical operations. In
terms of performance and security, Ecsc-l2g was slower, but it provided high level of security against all possible cryptanalysis attacks
