Abstract:

For the purpose of solving the problems of low query rate, inefficiency, and non-traceability in the existing digital anti-counterfeiting systems, a new anti-counterfeiting scheme based on chameleon signature without key exposure is proposed. The scheme can effectively improve the query rate of the system, strengthen the data integrity, resist the brute force attack, and distinguish the true products from bogus ones. Therefore, it is more suitable for anti-counterfeiting digital products in the electronic commerce infrastructure.

Key words: cryptography, digital signatures, digital anti-counterfeiting, electronic commerce
