ESP an an IPSec protocol used for encryption, ESP = Encapsulating Security
Payload [RFC 2406]. With this protocol you can garauntee confidentiality and
privacy by encrytpion.
A companion protocol, Authentication Header (AH) [RFC 2402], is used to insure
non-repudiation, i.e. you are who you say you are, undeniably. Many VPNs are
created using both protocols for true security of IP packets.
These protocols are implemented at the network layer (layer 3)
The best place to look for information on ESP is with the IETF, particularly the
IPSEC working Group.
The document that you should reference which is the basis for this protocol is:
RFC 2401, IPSEC, Security Architecture for the Internet.
The fundamental components of IPSec as defined by the RFC are:
a. Security Protocols -- Authentication Header (AH) and
Encapsulating Security Payload (ESP)
b. Security Associations -- what they are and how they work,
how they are managed, associated processing
c. Key Management -- manual and automatic (The Internet Key
Exchange (IKE))
d. Algorithms for authentication and encryption

Hope this helps in your research!
