Full Disclosure: Re: НА: WPA attack improved t o 1min, MITM

Hello M. B.,

Symmetric ciphers are much less computationally intensive than 
asymmetric ciphers. So, in a situation where one has to encrypt and 
decrypt a lot of data quickly (as in the WPA setting) its better to use 
a symmetric cipher.
