Securing a network wired or wireless for network administrator has been a big challenges for network administrators in the present day of Internet usage. This project presents ECDSA Cryptosystem as a solution to the problem been faced by network administrators and Engineers. The Elliptic Curve Digital Signature Algorithm (ECDSA) is the elliptic curve analogue of the Digital Signature Algorithm (DSA) with the attractiveness that there is no sub exponential algorithm known to solve the elliptic curve discrete logarithm problem on a properly chosen elliptic curve. ECDSA was used generally to secure information from a personal digital Assistant (PDA) and the result show the high security strength of ECC.
