ECDSA authentication for IKE SA and AES-GCM encryption for IPsec SA

You can configure the Elliptic Curve Digital Signature Algorithm (ECDSA) authentication method for an IKE security association (SA) and the Advanced Encryption Standard in Galois/Counter Mode (AES-GCM) encryption algorithm for an IPsec SA for MS-MPCs and MS-MICs. Junos OS supports the ECDSA 256-bit and 384-bit moduli methods and the AES-GCM 128-bit, 192-bit, and 256-bit encryption algorithms.
