  • AES Counter Mode (AES-CTR) is used in IKEv2 and ESP

  • How AES-CTR is used in ESP is defined in RFC3686

  • RFC4307: Crypto Algorithms for IKEv2

    3.1.3. IKEv2 Transform Type 1 Algorithms Name Number Defined In Status RESERVED 0 ENCR_3DES 3 [RFC2451] MUST- ENCR_NULL 11 [RFC2410] MAY ENCR_AES_CBC 12 [AES-CBC] SHOULD+ENCR_AES_CTR13 [AES-CTR] SHOULD

  • How IKEv2 use AES-CTR need to be defined. This document gives definition that how AES_CTR is used in IKEv2

    • Key size, rounds, block size

    • Initialization Vector, Counter Block format

    • IKEv2 conventions
