Abstract: Elliptic Curve Cryptography (ECC) is a public key cryptosystem with a security level determined by discrete logarithm problem called Elliptic Curve Discrete Logarithm Problem (ECDLP). John M. Pollard proposed an algorithm for discrete logarithm problem based on Monte Carlo method and known as Pollard Rho algorithm. The best current bruteforce attack for ECC is Pollard Rho algorithm. In this research we implement modified Pollard Rho algorithm on ECC over GF (241). As the result, the runtime of Pollard Rho algorithm increases exponentially with the increase of the ECC key length. This work also presents the estimated runtime of Pollard Rho attack on ECC over longer bits. [ABSTRACT FROM AUTHOR]

Abstract: A novel method of concealing information is proposed. Encrypted data is mixed with noise to add the security. The cost of an attack increases linearly with the size of the added noise. Since generating noise is cheap, the size of noise can be as large as possible. However, there are issues in automatically detecting and separating noise in the intended recipient end. This stegocrypto method also provides protection from traffic analysis attack. [ABSTRACT FROM AUTHOR]
