"It is therefore necessary that information secrecy and disclosure arrangements should be in place not only to protect information but also to enable the disclosure of information in appropriately controlled circumstances".
Moreover, information secrecy in multiple access channels (MAC) was studied in [8-10], and information secrecy in single-input single-output (SISO) fading channels was also studied in [11-13] [11-13]
In addition, for balancing the cost of system and secrecy performance, we also study some suboptimal schemes to improve information secrecy.
In this paper, we study information secrecy of SWIPT using zero-forcing beamforming which has lower computational complexity than the algorithm proposed in [26].
To guarantee information secrecy using Wyner's model, the channel condition of the legitimate user is required to be better than that of the eavesdropper.
Recently, an interesting way to achieve the secrecy using the aided noise was proposed in [14], where the information secrecy could be guaranteed even when the channel condition of the legitimate user is worse than that of the eavesdropper.

Robin McKie, science editor For a long time now, since digital media became the defining characteristic of our age, a revolution in information and secrecy has been predicted.
This is especially so for systems that handle financial transactions or confidential, classified or other information whose secrecy and integrity are critical.

Information theoretic secrecy was initiated by Wyner in his seminal work [1], where he introduced the wiretap channel and established the capacity-equivocation region of the degraded wiretap channel.
Frank Marshall remarked, "In today's information age, secrecy has been a real challenge..
