The cipher a block code is taken under, which the code borrows.

Implementations

impl BlockMicKey

pub fn new(data_block_int_key: &[u8; 16]) -> BlockMicKey

Prepares the key a block’s code is taken under.

Arguments

• data_block_int_key - the key data_block_int_key derived.

Returns

The prepared key.

pub fn start( &self, session_cnt: u16, frag_index: u8, descriptor: [u8; 4], block_len: u32, ) -> BlockMic<'_>

Starts a code over one session’s block.

Arguments

• session_cnt - the session counter the setup carried.
• frag_index - which of the device’s sessions this is.
• descriptor - the four bytes the setup described the block with.
• block_len - the length of the block in bytes, without its padding.

Returns
