加密算法实现
Pegwit is a program for performing public key file encryption
and authentication.
Encryption means that pegwit allows you to keep the information
in files you send by email (or other means) confidential.
Eavesdroppers will not be able to read the email.
Authentication allows you to c ...

书籍 Emerging Technologies in Wireless LANs Theory
Wireless Fidelity (Wi-Fi) networks have become mainstream over the last few years. What
started out as cable replacement for static desktops in indoor networks has been extended
to fully mobile broadband applications involving moving vehicles, high-speed trains, and
even airplanes.
书籍 Radio Frequency Identification and Sensors
There is an unprecedented enthusiasm for radio frequency
identification (RFID) technologies today. RFID is based on the
exchange of information carried by electromagnetic waves between a
label, or tag, and a reader. This technology is currently in full
economic expansion, which has manifested itself ...
