In this chapter, we perform a security analysis of the proposed model, examining it from the perspectives of collusion attacks, fairness, and its effectiveness as legal evidence.
Resistance to collusion attack,
In the proposed model, the attacker cannot predict which node will be selected as the calculation node by utilizing cryptographic hash functions, signature technology, and Algorand's security properties, so the possibility of collusion attack is virtually negligible.
Next, fairness.
In the proposed model, the SC resolves disputes by verifying commitments or signatures, identifying dishonest participants, and enforcing penalties. By leveraging cryptographic hash functions, commitment schemes, and signature schemes, the model ensures fairness through appropriate penalties and rewards for DO, DR, and CN.
