Ip Sec Internet Security Basic Structure

The IPsec suite is an  open standard . IPsec uses the following  protocols  to perform various functions: Authentication Headers (AH)  provide connectionless  integrity  and data origin  authentication  for IP  datagrams  and provides protection against  replay attacks . Encapsulating Security Payloads (ESP)  provide  confidentiality , data-origin  authentication , connectionless  integrity , an anti-replay service (a form of partial sequence integrity), and limited traffic-flow confidentiality. Security Associations (SA)  provide the bundle of algorithms and data that provide the parameters necessary to AH and/or ESP operations. The  Internet Security Association and Key Management Protocol  (ISAKMP) provides a framework for authentication and key exchange, with actual authenticated keying material provided either by manual configuration with pre-shared keys,  Internet Key Exch...
