3.2. Integrity Algorithms

The integrity algorithm employed for the ICV computation is specified by the SA. For point-to-point communication, suitable integrity algorithms include keyed Message Authentication Codes (MACs) based on symmetric encryption algorithms (e.g., AES [AES]) or on one-way hash functions (e.g., MD5, SHA-1, SHA-256, etc.). For multicast communication, a variety of cryptographic strategies for providing integrity have been developed and research continues in this area.
