• Satellite P200-157: Atheros AR5006EG WLan - AES encryption in question WPA

  Hello, sorry for my English.

  I bought a SATELLITE P200-157 with VISTA OEM 2 months, since I can't use WPA with Atheros AR5006EG AES encryption.

  The LAN does not work because three other computers are connected in wifi on the same router. With the Toshiba pc, I just can be connected to the WLAN key if my router WEP or WPA - PSK TKIP. in WPA - PSK AES/CCMP or TKIP + AES it does not work.
  When the SATELLITE is unable to connect to the WIFI network, it return when connecting try 'Abnormally long network connection' = connection too long and after vista let me choose between a diagnosis of the problem or borrowed from another ESSID.

  Did I missed something let work AES encryption? Thank you for helping me, I have no idea to solve this problem.

  Hello

  As far as I know all this (encryption) WLAN settings must operate if the material and the pre-installed driver supports all this. I'm afraid that in your case, he can't do it because the wireless network card and all modes of AES (Advanced Encryption Standard) encryption option are not supported.

• [WRT160NL] Problem with the only AES encryption

  Hello

  I have problems after changing the shape of TKIP or AES to AES encryption. After that everything works OK for a few minutes, then I'm 100% loss when ping anything (including the router). After waiting a few minutes connection starts to work again, and everything is repeated. All the time I'm connected. If I reconnect everything works for a few minutes and then I'm once again, this situation. Return to TKIP or AES does not change this behavior until the reboot of the router. I've got second laptop computer connected through wired interface and it work without problem. My card is: Intel WiFi Link 5100. Settings on the router:

  Firmware version: 1.00.01 B17 may 12, 2009

  Network mode: wireless - n only

  Channel width: wide angle: 40 MHz channel

  Scale channel: Auto

  Security mode: WPA2 Personal

  Does anyone have similar problems? Any ideas?

  Kind regards

  Try to re-flash the firmware on the router and re - configure the router from scratch. You can download the firmware from www.linksys.com/downloads.After re-flashing the firmware, reset the router for 30-35 seconds, power cycle the router and then re - configure from scratch.

• AES encryption on ergonomic sculpt desktop (L5V-00001) wireless?

  I was wondering if I can use the keyboard in a business environment.

  AES encryption is not mentioned in the technical data sheet of the L5V, although products in earlier versions "2.4 ghz wireless protocol owner" of microsoft seem to have AES encryption.

  Hello

  Thanks for posting your question on the Microsoft Community forums.

  Ideally, the keyboard can be used in any environment, provided he has the permission to do so. I recommend you contact the local, the IT team in your office who would be more that probably you do know if you have access to use it.

  Alternatively, you can also re - post your query on the TechNet forums to get help. Consult the following link:

• Support for hardware AES encryption

  Hello

  I have a router 1721 configured with an IPSec for a 3000 VPN tunnel.

  I tried to use the AES-256 encryption method, but when I try to create the game of transformation on the router, the following message appears

  ++++++++++++++++++++++++++++++++++++

  XXX (config) #crypto ipsec transform-set esp - aes 256 esp-md5-hmac myset2

  ATTENTION: hardware encryption does not support transformation

  ESP - aes 256 in IPSec transform myset2

  ++++++++++++++++++++++++++++++++++++

  Is that mean that the AES encryption would be via the software?

  Any idea what hardware encryption support be available for AES?

  Cordially------Naman

  Yes, AES is currently done in software only. We are coming up with a range of new hardware accelerators that will make both 3DES and AES, no word officially on when they will be released, sorry.

• Activation of the AES encryption on the network without WIRE of M30x-130 adapter

  How to enable encryption of data Advanced Encryption Standard (AES) on the WLAN of my laptop Satellite M30X-130 adapter? The LOCAL (internal) network card is an Intel PRO/Wireless 2200BG driver version is 8.0.12.20000 driver date: 08/03/2004 OS: Windows XP home SP2 according to TOSHIBA Satellite M30X user manual, this should be possible. My wireless router and the wireless in my desktop PC Adapter use AES data encryption and WPA - PSK network authentication. I can activate authentication network WPA - PSK on the laptop, but I can't select (only TKIP) AES data encryption.

  Kind regards

  There are new drivers available for the Intel WiFi card on the Intel Web site:

  http://support.Intel.com/support/wireless/WLAN/sb/CS-010623.htm

  If you install them, also install the tool Intel PROSet / Wireless, has its much better than the Wireless Zero Configuration tool Windows XP SP2 and it also has an option for AES data encryption.

• AES encryption key strength

  Hi all

  I need to create an application that decrypts the encrypted data using AES with a 512-bit key. What I need to know, is that we can create a key length of 512-bit AES? The documentation says that we can create a key of length up to 256 bits. If this is the case, is it possible that I can add my own implementation of 512-bit AES key, or do I have to reduce the power of key used to encrypt the data initially?

  Thank you

  Basilio

  AES doesn't have a 512-bit key. It seems I'm in the need to check my data entry!

• Xor may be crack the NoPadding/CFB-AES encryption-

  Hello
  Looks like a password can be discovered based on the numerical value of an old known password (using the same key).
  
  For example
  In case I have an obvious password: AAA
  and I have the password enrypted form of bytes: crypt (AAA).
  
  I can decrypt any password based on the result of the Xor of the clear and encrypted password: (AAA xor crypt (AAA))
  BBB = crypt (BBB) xor (xor crypt (AAA) AAA)
  It looks like a security problem.
  Is this a bug of java or mine?
  BTW, if you use AES/CFB8/NoPadding, this is not the case.

  Moderator: added [ code] tags to make the code readable. 

  This is your bug, because you randomly pick a mode and a method without really understanding them. Just look at the definition of [https://secure.wikimedia.org/wikipedia/en/wiki/Block_cipher_modes_of_operation#Cipher_feedback_.28CFB.29]

  Now, look at what your function "crypt". You use a fixed iv for everything, we just label the IV. So crypt ('AAA') = AES (key, iv) xor "AAA". That's why crypt ('AAA') xor 'AAA' = AES (key, iv). You should be able to understand what crypt('BBB") xor xor crypt ('AAA')"AAA ".

• Broadcom 4313 802.11b/g/n does not not on WPA2-PSK AES encryption.

  Hi, I just bought this adapter WLAN HP G62-b13SA Notebook PC is Broadcom 4313 802.11b/g/n his work well on WPA - PSK TKIP, but when I am trying to connect to my WIFI with WPA2-PSK AES or TKIP its not connecting any tried the upgrade and downgrade the driver but still no problem solved. same did the same thing with the ACCESS POINT which is Zyxel G-570. ideas how its going to work or it just does not support WPA2 to all?

  I had a similar problem with this network adapter. I could see the networks, the signal strength was excellent, but whenever I tried to connect, it failed. Several times he connected successfully, but the connection lost after a few minutes. In any case, I managed to fix after spending several hours playing with the options on the Advanced page of the driver. That's what I have now:

  802.11n preamble: Mixed Mode (this is a must if you are networked mixed g/n)

  Afterburner: disabled (not sure about that)

  AP compatibility mode: superior performance (I have a router standards)

  Bluetooth collaboration: disable (everything started work immediately after I disabled it)

  BT - AMP: disabled (not sure about that)

  Mixed cell support: disabled (this is not necessary for typical wifi networks)

  Technology XPress (TM): disabled (not sure, that's something for the performance of g)

  Other options are default values. I use a pilot boarded through Windows Update.

• Length of hash for AES encryption

  Which versions of IOS support AES 512?

  There is no 512 not associated to the AES standard, I am aware, the algorithm is based on 128, 192 and 256 bits.

  Any IOS with a k9 images support AES as it is part of the IPsec standards.

  Have a look here, good link to IPsec standards.

• Encryption AES/ECB/PKCS7Padding

  Dear developers

  I am converting an application from Android native BlackBerry 10. The application uses AES to encrypt the data. So I went looking for how to do in BlackBerry 10 but it seems not as simple as that. In Java, it looks like this:

  Byte [] arrayOfByte1 = HexToByte (key);
  Byte [] arrayOfByte2 = data.getBytes ("UTF8");

  SecretKeySpec localSecretKeySpec = new SecretKeySpec (arrayOfByte1, "AES");

  LocalCipher cipher = Cipher.getInstance("AES/ECB/PKCS7Padding");
  localCipher.init (1, localSecretKeySpec);

  Var str As String = Base64.encodeBytes (localCipher.doFinal (arrayOfByte2));

  But how can I easily achieve in 10 BlackBerry? I already tried with the download of this example:

  https://www.dropbox.com/s/czxmuhgzd8ak1zz/AesAlgoSample.zip

  But how to add padding to it? Encryption thing a little hard on BB10...

  https://twitter.com/robbieDubya of BlackBerry has created a nice AESCryptoDemo for waterfalls. I could follow through it and extract pieces I used in a Python application to operate the AES encryption. It includes pad/unpad routines. Should be all you need.

  Who have a 802.11 radio access point g should support AES.  According to the part number you gave this AP has a 802. 11 b radio except if it has been upgraded.  This radio will not support AES encryption.

• Error encryption AES-CNS-9053.

  Dear all,
  
  We are facing a problem with one of our customer while doing the synchronization process whenever the synchronization happens on the client side the client gets the error message on the screen
  
  * "MS-9053 AES encryption error" * "
  
  When we checked in the Ol_sync.log file we get the error
  
  * "'MISTAKE', CNS-9053," 2009-10-09 16:24:33 "," AES encryption error.: "," Clientname"" * "
  
  but the records of customers flows to the server without any error in the queue of the error and the server.
  
  When I tried to look for it I can't get something related to this error
  Please suggest,
  
  Thanks in advance,
  
  Kind regards

  Gary, I think that the mistake of the AES is attributed to the version of the JVM, the client uses. There was questions built between the two versions of Java 1.4_4 and persists until 1.4_12. JVM 1.5 had similar questions that encryption AES of Oracle Lite may have problems with as well. If only a few clients experience this problem, I recommend to see what they have for installed java.
