Description
Performs one-way or mutual authentication using the specified key
Checks the output MAC generated by the Auth command or by reading a counter using
the counter command on a second ATAES132 device
Computes the input MAC required to execute the Auth command or to increment a
counter using the counter command on a second ATAES132 device
Reads 1 to 32 bytes of data from user memory or the configuration memory. Returns
cleartext data.
Increments a monontonic counter and/or returns the counter value
Processes a seed value through the internal crunch engine. This function is used to
detect clones.
Checks the output MAC and decrypts data which was encrypted by the EncRead
command
Decrypts 16 or 32 bytes of data provided by the host after verifying the integrity MAC
Encrypts 1 to 32 bytes of data from user memory and returns the encrypted data and
integrity MAC
Encrypts 16 or 32 bytes of plaintext data provided by the host
Writes 1 to 32 bytes of encrypted data into the user memory or key memory after
verifying the integrity MAC
Returns device information: the MacCount, authentication status, or the hardware revision
code
Generates a random number, stores it in key memory and returns the encrypted key to
the host
Encrypts a key for export to an ATAES132 device. Optionally generates the key being
exported.
Decrypts and writes a key which was output by the KeyExport command or KeyCompute
command
Writes an encrypted key to key memory after verifying the integrity MAC
Transfers a key from user memory into the key memory or into the VolatileKey register
Performs a single AES-ECB mode operation on 16 bytes of data provided by the host
Permanently locks the configuration memory or key memory. Locked memory can never
be unlocked.
Generates a 128 bit nonce using the internal random number generator for use by the
cryptographic commands. This command can also be used to write a host nonce directly
into the Nonce register.
Generates a nonce in a manner which allows two ATAES132 devices to have identical
nonce values
Returns a 128 bit random number from the internal random number generator
Resets the device, clearing the cryptographic status
Places the device in the sleep state or standby state to reduce power consumption
Measures the die temperature
Encrypts data and generates the input MAC required to execute the EncWrite command
