Wireless LAN [WHR2-G54] trial description 4
The effective speed of WPA

There is TKIP and AES in the encoding system of WPA which is equipped in WHR2-G54, but is the respective effective speed probably to be which?This time, we had decided to try measuring the effective speed of the encoding system of WPA.

TKIP and AES

TKIP and AES are equipped in WHR2-G54 as the encoding system of WPA.Here, from the help of WHR2-G54, it will try quoting the explanation of the same encoding system.

TKIP (Temporal Key Integrity Protocol) with the cryptographic technology which expands WEP.The identical using selfishness, the vulnerability of WEP measure is done, it is encoding function of the security standard “WPA (Wi-Fi Protected Acces) which” the Wi-Fi alliance enacts.

After making IV (Initialization Vector, initialization vectoring) 24bit 48bit which is the vulnerability of WEP, because equality IV is not used, the tool which analyzes WEP on the basis of equality IV is nullified.
It encodes with the RC4 key which differs to every packet
Alteration detection is done with another key from encoding

AES (Advanced Encryption Standard) and isIEEE802.11iencryption method has been developed in the next generation. WEP encryption method causes the vulnerability has been adopted (RC4cipher) be due to decoding technique itself is present in the, TKIP improvement of vulnerability, but has been in, what was fundamentally review the encryption method itself AES is. TKIP for processing by the encryption software is, communication speed10~20%whereas down, AES order to handle in hardware encryption, it is characterized by great speed down there is no.
(feature)
· adopted encryption method used by the u.s. government, decoding method does not exist at the moment
· hardware for processing, without throughput degradation due to encryption

referring to the help of the above, still use the hardware processingAESis where you want to use more. so, what’s the difference between the actual speed of the extent to which.

standard that is attached to the initial product shipment client manager is, TKIPorAESresponse and has seen. therefore, here is currentlyTKIPorAESthat corresponds to the WindowsXP SP1 of wireless network connection i decided to take advantage of the. wireless network connection in order to use, you will need the following requirements:.

-BUFFALOdownload the latest version of the driver side of the cordless handset from the site of, to refresh the driver.
-WindowsXPtheSP1from then, Microsoftfrom the site of this patch shed.

also, BUFFALOpr because i am also like the following message from our, i will introduce.

effective speed

measurement of the effective rate is finally. it should be noted, in this survey, i decided to give the number as a representative value that appears most frequently out of a number of times survey.

first, if you do not want is the effective speed of encryption.

ftp: n/a bytes received in 1.55Seconds n/a Kbytes/sec. (about29.8Mbps)

then, TKIPis the effective speed of setting the.

ftp: n/a bytes received in 1.62Seconds n/a Kbytes/sec. (about28.5Mbps)

then, AESis the effective speed of setting the.

ftp: n/a bytes received in 1.59Seconds n/a Kbytes/sec. (about29.0Mbps)

if you do not want the speed of encryption is about 29.8Mbps has become, IEEE802.11ghas become a fast speed. TKIPorAESif you set the, each 28.5Mbps / 29.0Mbps although slightly slower, not late enough to experience. particularlyAESis, there is only you are using the hardware, decrease in speedTKIPhas become less. if this, alsoAEScustomers who take advantage of a good idea. it should be noted, the measurement environment, server/both the client1GHzof classCPUis a computer equipped with a.

in the above survey key update interval the0second (if you do not update the key) i was investigated in an environment where, this1i tried to research as to set the second. WHR2-G54the help of the, you can specify time, 0~3600seconds. too short a specified time(few seconds~number10second), load is higher, transmissions may become unstable. there is a, how slow was not particularly. normally, in relation to security, 60a good idea if you set the update interval for the second degree.
