1. A method for providing electromagnetic based secure contact-less integrity verification for an integrated circuit, the method comprising:
mapping a signal to a pseudo-random number generator (PRNG) seed value;
generating a PRNG output digital signal based on the PRNG seed value;
encrypting the PRNG output digital signal based on a cipher function and a key; and
generating an electromagnetic signal associated with the PRNG output digital signal to facilitate non-contact sensing of the electromagnetic signal by a probing system.
