snowpolodavos.com - The fundamentals of creating a VPN are Authentication, strong Encryption and a method of secure Key Exchange. Authenticate the users, securely exchange keys for encryption then encrypt the data using the generated keys.
Authentication is used to validate a users identity using one or more of a number of methods:
Something you have - can be a key card, a security pass, drivers licence, a passport or similar. The possession of one of the above items is usually enough to confirm the identity of the holder. The problem with this is that the device can be lost or stolen, and sometimes used by other persons. snowpolodavos.com
Something you know - a password, pass phrase or some other known information that can be used to calculate function from a secret message.
Something you are - A physical characteristic of your body such as your finger print, the retina print of your eye or your DNA.
Encryption is a means of taking some plain readable text into a cipher text utilizing some form of algorithmic mapping. The intended receiver of such a cipher text must have the means to reverse the process by knowing the same algorithm, but an attacker cannot know the process.
Encryption systems must use mathematically complex algorithms so as to provide a good enough deterrent from attackers to be able to use some brute force method of calculating the algorithm in use. Two common methods of encryption are Symmetric Encryption Systems and Public Key Encryption Systems:
Symmetric encryption simply uses an identical key for encryption of the plain text and decryption of the cipher text. and decryption at both ends. The encryptor applies the key to the plain text data which results in a cipher text. The decryptor reverses the by applying the same key to the cipher text to reveal the plain text data. The most common symmetric encryption system is the Data Encryption Standard (DES), of which there are several variations.

The Lithium Ion Battery Advantages
msmbe.org - Li-ion battery or Lithium ion battery is one of several types of rechargeable batteries. During the discharge process, the lithium ions travel from the anode to the cathode and vice versa. Let's know a bit more about the advantages of lithium-ion batteries.
How do these batteries work?
Different types of li-ion batteries make use of different types of cathodes. The cathodes are made of lithium molecules. Generally, the anodes are made of carbon. As with other types of batteries, the chemical reaction that happen between the cathode, anode and the electrolyte generate electric current. Aside from this, the stuff used for these will affect the cost, capacity, performance and the safety of a certain type of battery. msmbe.org
Li-ion batteries, for instance, that feature a lithium cobalt oxide cathode can give you a bit higher capacity. However, they are more reactive because of the lower thermal capacities. Another great option is the lithium iron phosphate. Their life cycle is 4-5 times longer. Moreover, their power density is around 10 times better.
These batteries are of various classes, but they are commonly used in portable or consumer devices like smartphones and laptops. Aside from this, this type of battery is also popular for use in aerospace, military and other electric automobiles.
