'This new generation of high-speed HF waveforms represent a major technical advance,' said Steve Elvy, director of engineering, Harris Corporation, RF Communications Division, Rochester, N.Y. 'The adoption of MIL-STD-188-110B as the NATO standard is a testimony to the design of the waveform and its implementation in the Harris RF-5710A modem.

Many routers provide WPA2-PSK (TKIP), WPA2-PSK (AES), and WPA2-PSK (TKIP/AES) as options. Choose the wrong one, though, and you’ll have a slower, less-secure network.Wired Equivalent Privacy (WEP), Wi-Fi Protected Access (WPA), and Wi-Fi Protected Access II (WPA2) are the primary security algorithms you’ll see when setting up a wireless network.

WEP is the oldest and has proven to be vulnerable as more and more security flaws have been discovered. WPA improved security, but is now also considered vulnerable to intrusion.

WPA2, while not perfect, is currently the most secure choice. Temporal Key Integrity Protocol (TKIP) and Advanced Encryption Standard (AES) are the two different types of encryption you’ll see used on networks secured with WPA2.

Let’s take a look at how they differ and which is best for you.RELATED. TKIPTKIP and AES are two different types of encryption that can be used by a Wi-Fi network. TKIP is actually an older encryption protocol introduced with WPA to replace the very-insecure WEP encryption at the time. TKIP is actually quite similar to WEP encryption. TKIP is no longer considered secure, and is now deprecated.

In other words, you shouldn’t be using it.AES is a more secure encryption protocol introduced with WPA2. AES isn’t some creaky standard developed specifically for Wi-Fi networks, either. It’s a serious worldwide encryption standard that’s even been adopted by the US government. For example, when you, it can use AES encryption for that. AES is generally considered quite secure, and the main weaknesses would be (prevented by using a strong passphrase) and.RELATED:The short version is that TKIP is an older encryption standard used by the WPA standard. AES is a newer Wi-Fi encryption solution used by the new-and-secure WPA2 standard. In theory, that’s the end of it.

But, depending on your router, just may not be good enough.While WPA2 is supposed to use AES for optimal security, it can also use TKIP where backward compatibility with legacy devices is needed. In such a state, devices that support WPA2 will connect with WPA2 and devices that support WPA will connect with WPA. So “WPA2” doesn’t always mean WPA2-AES. However, on devices without a visible “TKIP” or “AES” option, WPA2 is generally synonymous with WPA2-AES.RELATED:And in case you’re wondering, the “PSK” in those names stands for “” — the pre-shared key is generally your encryption passphrase.

This distinguishes it from WPA-Enterprise, which uses a RADIUS server to hand out unique keys on larger corporate or government Wi-Fi networks. Wi-Fi Security Modes ExplainedConfused yet?

We’re not surprised. But all you really need to do is hunt down the one, most secure option in the list that works with your devices. Here are the options you’re likely to see on your router:RELATED:. Open (risky): Open Wi-Fi networks have no passphrase.

You shouldn’t set up an open Wi-Fi network—seriously,. WEP 64 (risky): The old WEP protocol standard is vulnerable and you really shouldn’t use it. WEP 128 (risky): This is WEP, but with a larger encryption key size.

It isn’t really any less vulnerable than WEP 64. WPA-PSK (TKIP): This uses the original version of the WPA protocol (essentially WPA1). It has been superseded by WPA2 and isn’t secure. WPA-PSK (AES): This uses the original WPA protocol, but replaces TKIP with the more modern AES encryption. It’s offered as a stopgap, but devices that support AES will almost always support WPA2, while devices that require WPA will almost never support AES encryption. So, this option makes little sense. WPA2-PSK (TKIP): This uses the modern WPA2 standard with older TKIP encryption. This isn’t secure, and is only a good idea if you have older devices that can’t connect to a WPA2-PSK (AES) network.

WPA2-PSK (AES): This is the most secure option. It uses WPA2, the latest Wi-Fi encryption standard, and the latest AES encryption protocol. You should be using this option. On some devices, you’ll just see the option “WPA2” or “WPA2-PSK.” If you do, it will probably just use AES, as that’s a common-sense choice.

WPAWPA2-PSK (TKIP/AES): Some devices offer—and even recommend—this mixed-mode option. This option enables both WPA and WPA2, with both TKIP and AES. This provides maximum compatibility with any ancient devices you might have, but also allows an attacker to breach your network by cracking the more vulnerable WPA and TKIP protocols.WPA2 certification became available in 2004, ten years ago. In 2006, WPA2 certification became mandatory. Any device manufactured after 2006 with a “Wi-Fi” logo must support WPA2 encryption.Since your Wi-Fi enabled devices are most likely newer than 8-10 years old, you should be fine just choosing WPA2-PSK (AES).

Select that option and then you can see if anything doesn’t work. If a device does stop working, you can always change it back. Although, if security is a concern, you might just want to buy a new device manufactured since 2006. WPA and TKIP Will Slow Your Wi-Fi DownRELATED:WPA and TKIP compatability options can also slow down your Wi-Fi network.

Many modern Wi-Fi routers that support will slow down to 54mbps if you enable WPA or TKIP in their options. They do this to ensure they’re compatible with these older devices.By comparison, even 802.11n supports up to 300mbps if you’re using WPA2 with AES. Theoretically, 802.11ac offers maximum speeds of 3.46 Gbps under optimum (read: perfect) conditions.On most routers we’ve seen, the options are generally WEP, WPA (TKIP), and WPA2 (AES)—with perhaps a WPA (TKIP) + WPA2 (AES) compatibility mode thrown in for good measure.If you do have an odd sort of router that offers WPA2 in either TKIP or AES flavors, choose AES. Almost all your devices will certainly work with it, and it’s faster and more secure. It’s an easy choice, as long as you can remember AES is the good one.Image Credit.
