Android gives a world-class platform for creating apps and games, as well as open marketplaces for distributing them instantly. The hackers can easily hack such open source application codes, edit their signatures, publish them over the internet and take control of devices which install those applications, to gain access to user’s personal information. To prevent this, an efficient digital signature scheme is needed. Thus a new system in which the mechanism of digital signature using elliptic curve cryptography has been proposed that gives the combined efficiency of Two Key Signature Scheme and Multi-signature Scheme. Multi-signature scheme is used to provide certifiable digital signatures that are signed many times rather than signing once. Each signature is signed using two key signature scheme of elliptic curve cryptography to increase the complexity of brute force attacks. Thus, it would be efficient digital signature approach that suits current mobile platforms such as Android.
