Syntax

content_copy zoom_out_map
encryption-algorithm (3des-cbc | des-cbc | aes-128-cbc | aes-128-gcm | aes-192-cbc | aes-256-cbc | aes-256-gcm);

Hierarchy Level

[edit security ike proposal ike-proposal-name],
[edit security ipsec proposal ipsec-proposal-name]

Description

Configure an IKE or IPsec encryption algorithm. Two algorithms are supported: Cipher Block Chaining (CBC) and Galois/Counter Mode (GCM). CBC is older than GCM and is less secure. GCM is considered more secure than CBC since it provides built-in authentication and integrity checks. GCM is also more efficient for parallel processing, which can result in better performance for larger datasets.

Options

  • 3des-cbc—Encryption algorithm with key size of 24 bytes; its key size is 192 bits long.

  • des-cbc—Encryption algorithm with key size of 8 bytes; its key size is 48 bits long.

  • aes-128-cbc—Advanced encryption algorithm that has a key size of 16 bytes; its key size is 128 bits long.

  • aes-128-gcm—AES GCM 128-bit encryption algorithm.

  • aes-192-cbc—Advanced encryption algorithm that has a key size of 24 bytes; its key size is 192 bits long.

  • aes-256-cbc—Advanced encryption algorithm that has a key size of 32 bytes; its key size is 256 bits long.

  • aes-256-gcm—AES GCM 256-bit encryption algorithm. For an IKE proposal, AES 256-bit authenticated encryption algorithm is supported with IKEv2 only. When this option is used, aes-256-gcm should be configured at the [edit security ipsec proposal proposal-name] hierarchy level, and the authentication-algorithm option should not be configured at the [edit security ike proposal proposal-name] hierarchy level.

Required Privilege Level

security—To view this statement in the configuration.

security-control—To add this statement to the configuration.

Release Information

Statement introduced before Junos OS Release 7.4.
