This may be a rather obscure point, but if a cryptographic device takes different amounts of time to encrypt and decrypt equal-length blocks of text with different contents, it is a cryptographic vulnerability and may also provide a covert channel. These time differences, however, have to be constant. If they are simply a function of processing load, there is no vulnerability. Latency is not a cryptosecurity issue, although, obviously, it can affect speech intelligibility. > > >""Matt Hill"" wrote in message >[EMAIL PROTECTED]">news:[EMAIL PROTECTED]... >> Good luck.. >> >> However you will get latency and jitter issues during the time the PIXs >> encrypt/decrypt the voice packets... >> >> Matt >> >> > -----Original Message----- >> > From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]] On Behalf >> Of >> > Simer Mayo >> > Sent: Friday, 10 January 2003 6:05 PM >> > To: [EMAIL PROTECTED] >> > Cc: [EMAIL PROTECTED] >> > Subject: VoIP from behind PIX >> > >> > 1.
