Hello Rajesh,
You need a SAM_AuthenticateHost if you want to do “maintaining commands”, e.g.: change or set new keys, change key version etc. If the SAM is prepared and all keys updated, you use it in Non-X-mode to authenticate PICCs in front of a reader. Here it depends on the MIFARE card type, which command you use. For instance you use SAM_AuthenticatePICC to authenticate to a DESFire with AES keys. Therefore no host authentication is required.
