Abstract—IP protection in smart cards is the most important aspect in the production process. Various solutions based on the idea of bit stream encryption have been proposed. In this paper SRAMPUF technology is used to obtain an acceptable security level in smart cards. At first, the strategy of SRAMPUF for producing physical unreachable code is used. Then the output of SRAMPUF is combined with customer’s password to generate a unique and highly secure code. This is based on a powerful encrypting method. At last the result of this process is sent to data-center for comparison with a predefined database and authentication purposes.
Index Terms—Challenge-response pair, IP arbiter, smart cards security, SRAM PUF.
