Resum
PKI can improve security of mobile payments but its complexity has made difficult its use in such environment. Certificate path validation is complex in PKI. This demands some storage and processing capacities to the verifier that can exceed the capabilities of mobile devices. In this paper, we propose TRUTHC to reduce computational cost of mobile payment authentication. TRUTHC replaces verification operations with hash operations. Results show a better reduction of the cost with ECDSA than with...
