Security extension for IEEE Std 1149.1.
Journal of Electronic Testing: Theory and Applications, Vol. 22, 2006, pp. 301-303.
A security extension for IEEE Std 1149.1 is proposed. It provides a locking mechanism
which prevents unauthorised users to interfere via test bus with the system normal
operation. The security extension requires small hardware overhead and allows full
conformance with IEEE Std 1149.1.
