Nettet21. okt. 2024 · Both AH and ESP rely on the field, Integrity Check Value (ICV), to verify data integrity and the authenticity of data origin. However, IPsec natively supports the computation of ICV through a hash-based or block-cipher message authentication code (MAC) instead of a digital signature. NettetThe IPsec AH protocol provides user authentication and integrity protection for packet headers and data. It may also provide replay protection and access protection but cannot encrypt any portion of packets.

NettetAuthentication algorithms verify the data integrity and authenticity of a message. Fireware supports three authentication algorithms: HMAC-MD5 (Hash Message Authentication Code — Message Digest Algorithm 5) MD5 produces a 128-bit (16 byte) message digest, which makes it faster than SHA1 or SHA2.
