Digital Signature Technology is replacing paper-based work for customers and employees in various industries and e-commercial environment. Digital Signature provides cryptographic services like authentication, non-repudiation, and integrity for the digital data. With the development of internet, Digital Signature becomes increasingly important for security because of its integrity and authenticity. It is an electronic signature that can be used to authenticate the identity of the sender. Digital Signature does not provide confidentiality until an encryption algorithm is applied. In this study, a new model of Digital Signature is introduced using the Elliptic Curve Digital Signature Algorithm (ECDSA)with an encryption technique Schmidt Samoa Cryptosystem. This model provides double layer security with encryption as well as signing protocol. Proposed model provides features like confidentiality, non-repudiation, and authenticity.
