IAPM (mode)


Integrity Aware Parallelizable Mode is a mode of operation for cryptographic block ciphers. As its name implies, it allows for a parallel mode of operation for higher throughput.

Encryption and authentication

At the time of its creation, IAPM was one of the first cipher modes to provide both authentication and privacy in a single pass.
IAPM was proposed for use in IPsec.
Other AEAD schemes also provide all of the single pass, privacy and authentication properties. IAPM has mostly been supplanted by Galois/Counter Mode.
