This document describes Next Generation Encryption (NGE) support on Cisco IOS® and Cisco IOS-XE platforms.
There are no specific requirements for this document.
The information in this document is based on these software and hardware versions:
Cisco IOS, multiple versions as noted in the table
Cisco IOS-XE, multiple versions as noted in the table
Multiple Cisco platforms as noted in the table
The information in this document was created from the devices in a specific lab environment. All of the devices used in this document started with a cleared (default) configuration. If your network is live, make sure that you understand the potential impact of any command.
The algorithms that make up NGE are the result of more than 30 years of global advances and evolution in cryptography. Each component of NGE has its own history, which depicts the diverse history of the NGE algorithms and their longstanding academic and community review. NGE comprises globally created, globally reviewed, and publicly available algorithms.
NGE algorithms are integrated into Internet Engineering Task Force (IETF), IEEE, and other international standards. As a result, NGE algorithms have been applied to the most recent and highly-secure protocols that protect user data, such as Internet Key Exchange Version 2 (IKEv2).
Types of cryptographic algorithms include:
Symmetric encryption -128-bit or 256-bit Advanced Encryption Standard (AES) in GCM (Galois/Counter mode)
Hash - Secure Hash Algorithms (SHA)-2 (SHA-256, SHA-384, and SHA-512)
Digital signatures -Elliptic Curve Digital Signature Algorithm (ECDSA)
Note 1: On the ISR G2 platform, if ECDH/ECDSA is configured, these cryptographic operations will be run in software irrespective of the cryptographic engine. AES-GCM-128 and AES-GCM-256 encryption algorithms have been supported for IKEv2 control plane protection since Version 15.4(2)T.
Note 2: ISR G2 CISCO86x/C86x does not have NGE support in the hardware crypto engine.
Note 3: ISR G2 CISCO88x/CISCO89x has hardware support for SHA-256 ONLY with Version 15.2(4)M3 or later.
Note 4: These C88x SKUs have no hardware support for NGE: C881SRST-K9, C881SRSTW-GN-A-K9, C881SRSTW-GN-E-K9, C881-CUBE-K9, C881-V-K9, C881G-U-K9, C881G-S-K9, C881G-V-K9, C881G-B-K9, C881G+7-K9, C881G+7-A-K9, C886SRST-K9, C886SRSTW-GN-E-K9, C886VA-CUBE-K9, C886VAG+7-K9, C887SRST-K9, C887SRSTW-GN-A-K9, C887SRSTW-GN-E-K9, C887VSRST-K9, C887VSRSTW-GNA-K9, C887VSRSTW-GNE-K9, C887VA-V-K9, C887VA-V-W-E-K9, C887VA-CUBE-K9, C887VAG-S-K9, C887VAG+7-K9, C887VAMG+7-K9, C888SRSTW-GN-A-K9, C888SRSTW-GN-E-K9, C888SRST-K9, C888ESRST-K9, C888ESRSTW-GNA-K9, C888ESRSTW-GNE-K9, C888-CUBE-K9, C888E-CUBE-K9, and C888EG+7-K9.
Note 5: Support for the NGE control plane (ECDH and ECDSA) has been introduced with Version XE3.7 (15.2(4)S). Initial control plane SHA-2 support was for IKEv2 only, with IKEv1 support added in Version XE3.10 (15.3(3)S). AES-GCM-128 and AES-GCM-256 encryption algorithms have been supported for IKEv2 control plane protection since Version XE3.12 (15.4(2)S) and 15.4(2)T. NGE dataplane support was added in Version XE3.8 (15.3(1)S) for Octeon based platforms only (ASR1001-X, ASR1002-X, ESP-100, and ESP-200); dataplane support is not available for other ASR platforms.
