Chapter 18. IEEE 802.1AE

IEEE 802.1AE is a standards-based Layer 2 encryption specification, enabling wire-rate encryption at gigabit (Gb) speeds. It provides for cryptographic confidentiality and integrity of all communications (that is, control, data, and management frames) between two adjacent 802.1AE-capable Layer 2 Ethernet ports. This chapter discusses the trends, challenges, and reasons you need to consider this technology.
