摘要：Indonesia e-cash system faced with some challenges. Lack of proper networkinfrastructure impedes the distribution of e-cash throughout the country. Most existing e-cashscheme designed for usage with proper network infrastructure, mainly for validating thetransaction. Existing peer-to-peer e-cash scheme also require proper network infrastructure,either for public key request or deposit the received e-cash. This paper proposed a novel ecashscheme by building its e-cash data as chain of transaction (block chain) using identitybasedsigncryption as its security mechanism. The combination of block chain and identitybasedsigncryption make the e-cash peer-to-peer, transferable, and able to operate on ad hocnetwork. The Markov chain evaluation show that the proposed scheme can achieve securityagainst forgery and double spending.
