The IEEE 1687 standard, which is commonly used for efficient access of on-chip instruments, could be exploited by an intruder and thus needs to be secured. One of the techniques to alleviate the vulnerability of 1687 network is to use a secure access protocol that is based on licensed access software, Chip ID and locking SIB. A licensed access software is generally used to gain control of the embedded instruments and use them as per requirement.
