Struct SecurityContext

pub struct SecurityContext<AEADBLKCIPH, KEYDESCLO>
where
    AEADBLKCIPH: NewBlockCipher + BlockCipher<BlockSize = U16>,
    KEYDESCLO: KeyDescriptorLookup<AEADBLKCIPH::KeySize>,
{
    pub euid: u64,
    pub frame_counter: u32,
    pub key_provider: KEYDESCLO,
    /* private fields */
}

A context that used to keep track of cryptographic properties that are necessary for securing/unsecuring frames

AEAD is the type that will provide an AEAD instance to be used for the encryption/decryption process

NONCEGEN is the type that will convert the nonce created using the 802.15.4 standard into a nonce of the size that can be accepted by the provided AEAD algorithm

Fields

euid: u64

The EUID used for calculating the nonce of outgoing frames

frame_counter: u32

The current frame counter

key_provider: KEYDESCLO

The key descriptor lookup to use to look up keys
