Perceptual coding takes advantage of the human ear, screening out a certain amount of sound that is perceived as noise. In perceptual coding you reduce or eliminate the sounds that the ear would perceive […]
- perfect forward secrecy
A key-establishment protocol, used to secure VPN communications. If one encryption key is compromised only data encrypted by that specific key is compromised. For perfect forward secrecy (PFS) to exist the key used to protect transmission of data must not be used to derive any additional keys.
