The document presents RACE, a report-based payment scheme designed for multihop wireless networks that promotes node cooperation while minimizing communication and processing overhead. Unlike traditional receipt-based methods, RACE uses lightweight payment reports verified by an accounting center, allowing for efficient identification and eviction of cheating nodes without false accusations. The proposed system shows significant reductions in overhead compared to existing schemes, making it suitable for practical micropayment applications.
A secure payment scheme with low communication and processing overhead for multihop wireless networks
- 1. A Secure Payment Scheme with Low Communication and Processing Overhead for Multihop Wireless Networks ABSTRACT: We propose RACE, a report-based payment scheme for multihop wireless networks to stimulate node cooperation, regulate packet transmission, and enforce fairness. The nodes submit lightweight payment reports (instead of receipts) to the accounting center (AC) and temporarily store undeniable security tokens called Evidences. The reports contain the alleged charges and rewards without security proofs, e.g., signatures. The AC can verify the payment by investigating the consistency of the reports, and clear the payment of the fair reports with almost no processing overhead or cryptographic operations. For cheating reports, the Evidences are requested to identify and evict the cheating nodes that submit incorrect reports. Instead of requesting the Evidences from all the nodes participating in the cheating reports, RACE can identify the cheating nodes with requesting few Evidences. Moreover, Evidence aggregation technique is used to reduce the Evidences’ storage area. Our analytical and simulation results demonstrate that RACE requires much less communication and processing overhead than the existing receipt-based schemes with acceptable payment clearance delay and storage area. This is essential for the effective implementation

Moreover, RACE can secure the payment and precisely identify the cheating nodes without false accusations. EXISTING SYSTEM: The existing payment schemes can be classified into tamper-proof-device (TPD)- based and receipt-based schemes. In TPD-based payment schemes, a TPD is installed in each node to store and manage its credit account and secure its operation. For receipt-based payment schemes, an offline central unit called the accounting center stores and manages the nodes’ credit accounts. The nodes usually submit undeniable proofs for relaying packets, called receipts, to the AC to update their credit accounts. DISADVANTAGES OF EXISTING SYSTEM: False accusations and missed detections Vulnerable to Collusion attacks Long time to identify cheaters
- 3. PROPOSED SYSTEM: In this paper, we propose RACE, a Report-based pAyment sChemE for MWNs. The nodes submit lightweight payment reports (instead of receipts) to the AC to update their credit accounts, and temporarily store undeniable security tokens called Evidences. The reports contain the alleged charges and rewards of different sessions without security proofs, e.g., signatures. The AC verifies the payment by investigating the consistency of the reports, and clears the payment of the fair reports with almost no cryptographic operations or computational overhead. For cheating reports, the Evidences are requested to identify and evict the cheating nodes that submit incorrect reports, e.g., to steal credits or pay less. In other words, the Evidences are used to resolve disputes when the nodes disagree about the payment. Instead of requesting the Evidences from all the nodes participating in the cheating reports, RACE can identify the cheating nodes with submitting and processing few Evidences. Moreover, Evidence aggregation technique is used to reduce the storage area of the Evidences. In RACE, Evidences are submitted and the AC applies cryptographic operations to verify them only in case of cheating, but the nodes always submit security tokens, e.g., signatures, and the AC always applies cryptographic operations to verify the payment in the existing receipt based schemes. RACE can clear the payment nearly without applying cryptographic operations and with submitting lightweight reports when Evidences are not frequently requested.
- 4. ADVANTAGES OF PROPOSED SYSTEM: Widespread cheating actions are not expected in civilian applications because the common users do not have the technical knowledge to tamper with their devices. Moreover, cheating nodes are evicted once they commit one cheating action and it is neither easy nor cheap to change identities. Our analytical and simulation results demonstrate that RACE requires much less communication and processing overhead than the existing receipt-based schemes with acceptable payment clearance delay and Evidences’ storage area, which is necessary to make the practical implementation of the payment scheme effective. Moreover, RACE can secure the payment and precisely identify the cheating nodes without false accusations or stealing credits. To the best of our knowledge, RACE is the first payment scheme that can verify the payment by investigating the consistency of the nodes’ reports without systematically submitting and processing security tokens and without false accusations. RACE is also the first scheme that uses the concept of Evidence to secure the payment and requires applying cryptographic operations in clearing the payment only in case of cheating. In overall we summarize: Lightweight payment reports (charges and rewards) without security proof Almost no cryptographic operations in clearing payments of fair reports
