ESP provides confidentiality. Optionally, ESP also provides integrity, authentication, anti-replay service, and limited traffic flow confidentiality. Options selected at the time of Security Association establishment determine provided services. For confidentiality, shared ESP supports shared key encryption algorithms, such as DES and Triple DES.
Encapsulating security payload. A mechanism for providing integrity and confidentiality to IP datagrams. In some circumstances it can also provide authentication to IP datagrams, depending on which algorithm or algorithm mode is used. It does not provide nonrepudiation and protection from traffic analysis.
Ethernet Sending of Packets
Encapsulated Security Payload. In a Virtual Private Network (VPN), a security protocol that provides data confidentiality and integrity.
encapsulating security payload. An IPSec protocol that provides confidentiality, in addition to authentication, integrity, and anti-replay. ESP can be used alone, in combination with AH, or nested with the Layer Two Tunneling Protocol (L2TP). ESP does not normally sign the entire packet unless it is being tunneled-ordinarily, just the data payload is protected, not the IP header.
encapsulating security payload. An extension header that provides integrity and confidentiality to datagrams. ESP is one of the five components of the IP Security Architecture (IPsec).
See Encapsulating Security Payload.
Encapsulating Security Payload. A provision of IPSec that encrypts and decrypts IP packets. The payload itself can be either the entire original packet (tunnel mode), or just the data portion (transport mode). The cryptography process is controlled by keys of various lengths employed in a variety of different algorithms.
Encapsulating Security Payload (RFC 2406) is a protocol that IPSec uses to encrypt data to ensure confidentiality.
Encapsulating Security Payload. IPSEC header that encrypts the contents of an IP packet. The most recent implementations of IPSEC may also provide authentication and anti-replay protection of the AH to the packets.
Encapsulating Security Payload is a protocol within the IPSec protocol suite that provides encryption services for tunnelled data.
Encapsulating Security Payload, privacy mechanism of IPSec
Encapsulating Security Payload. A security protocol which provides data confidentiality, data integrity, and protection services, optional data origin authentication, and anti-replay services. ESP encapsulates the data to be protected. ESP can be used either by itself or in conjunction with AH. ESP can be configured with DES or Triple DES. Both the older RFC 1829 ESP and the updated ESP protocol are implemented. RFC 1829 specifies DES-CBC as the encryption algorithm; it does not provide data authentication or anti-replay services. RFC 2406 documents the latest version of ESP. The updated ESP protocol is per the latest version of the "IP Encapsulating Security Payload" Internet Draft (draft-ietf-ipsec-esp-v2-xx.txt). The updated ESP protocol allows for the use of various cipher algorithms and (optionally) various authentication algorithms. Cisco IOS software implements the mandatory 56-bit DES-CBC with Explicit IV as the encryption algorithm, and MD5 or SHA (HMAC variants) as the authentication algorithms. The updated ESP protocol provides anti-replay services.
ESP (HMAC-MD5). Encapsulation with Authentication Header (Keyed-Hashing for Message Authentication-Message Digest 5) encryption and authentication algorithm. See ESP and AH. HMAC-MD5 provides source authentication for each network packet using the HMAC-MD5 hash algorithm. Also, provides optional anti-replay services, in which a receiving peer can protect itself against replay attacks by denying old or duplicate packets. MD5 performs faster and provides less secure authentication than does SHA. Supported combined with DES-CBC. RFC 2406 documents the latest version of ESP. RFC 2403 documents the latest version of MD5.
ESP(HMAC-SHA). Encapsulation with Authentication Header (Keyed-Hashing for Message Authentication-Secure Hash Algorithm) encryption and authentication algorithm. See ESP and AH. SHA provides source authentication for each network packet using the HMAC-SHA hash algorithm. Also, provides optional anti-replay services, in which a receiving peer can protect itself against replay attacks by denying old or duplicate packets. SHA provides more secure authentication and performs slower than does MD5. Supported combined with DES-CBC and Triple-DES. RFC 2406 documents the latest version of ESP. RFC 2404 documents the latest version of SHA.
ESP (Triple DES). Encapsulation (Triple Data Encryption Standard) encryption algorithm. See ESP. Triple DES provides 168-bit encryption and processes each cipher block three times with three different keys to increase encryption strength. Triple DES provides more secure encryption and performs slower than does DES-CBC. Supported combined with HMAC-MD5 or HMAC-SHA. RFC 2406 documents the latest version of ESP.

Encapsulating Security Payload. The ESP provides confidentiality (encryption).
(Encapsulating Security Payload) An encryption and validation standard used with IPsec.
Encapsulating Security Payload. A mechanism to provide confidentiality and integrity protection to IP datagrams.
Encapsulating Security Protection. One of two protocol choices (the other is Authentication Header) in Internet Protocol Security (IPsec). IPsec protocol controls if confidentiality and/or message integrity are used to protect a data packet.
Encapsulating Security Payload. A protocol for securing packet flows for IPSec using encryption, data integrity checks, and sender authentication, which are added as a header to an IP packet. If an ESP packet is successfully decrypted, and no other party knows the secret key the peers share, the packet was not wiretapped in transit. See also AH.
Encapsulating Security Payload. A fundamental component of IPSec-compliant VPNs. Specifies both encryption of an IP packet, as well as data integrity checks and sender authentication, which are added as a header to the IP packet.
A security system in which IP datagram data is encrypted.
(Encapsulating Security Payload) An IPSec protocol used in WatchGuard's Branch Office VPN. ESP encrypts all or part of a packet of data in a way that assures confidentiality even though the data travels over the public Internet. It provides data integrity, and offers assurance of the identity of the data's sender (authentication). For details, see RFC 1827.
This acronym means "Encapsulating Security Payload", and refers to a protocol, within the IPSEC suite of protocols, for the privacy protection of IP data. The ESP protocol is described in RFC 1827.
