Encryption algorithms used in IKE
IKEEncryption algorithms are used to ensure confidentiality of the messages
exchanged during IKE negotiations. AES stands for Advanced Encryption Standards.
AES_128 uses 128-bit keys whereas AES_256 uses 256-bit keys for encryption and
decryption. AES_128 and AES_256 use CBC mode of encryption. AES_GCM stands for
Advanced Encryption Standard(AES) in Galois/Counter Mode(GCM) and is used to
provide both confidentiality and data origin authentication. AES_GCM composed
of two separate functions one for encryption(AES) and one for authentication(GMAC).
AES_GCM algorithms will be available with IKE_V2 version only.
AES_GMAC_128 uses 128-bit keys.
AES_GMAC_192 uses 192-bit keys.
AES_GMAC_256 uses 256-bit keys.
