Encryption and authentication
IAPM was the first cipher mode created to provide both authentication and privacy in a single pass. Previously, two passes would be required to achieve both benefits: for example the first pass using DES in CBC mode and the second pass authenticating with HMAC-MD5. IAPM allows for a single pass achieving both authentication and privacy.
