ABSTRACT:
An integrated circuit (IC) may include at least one smart card memory for storing a set of default requests and at least one alternate request for each default request. The IC may further include a microprocessor connected to the at least one smart card memory for communicating with a host device using the default requests and alternate requests. The microprocessor may selectively switch between using the default requests and the alternate requests when communicating with the host device. As such, this provides a “moving target” which makes it difficult for would-be hackers to determine which requests are used for which smart card operations and, thus, to decipher and interfere with data communications.
