Abstract Abstract
IPsec ESP with AES-CBC, AES-CTR, AES-CCM or AES-GCM sends an IV in IPsec ESP with AES-CBC, AES-CTR, AES-CCM or AES-GCM sends an IV in
each IP packet, which represents 8 or 16 additional bytes. each IP packet, which represents 8 or 16 additional bytes.
In some context, such as IoT, the cost of sending bytes over In some context, such as IoT, the cost of sending bytes over
computing these bytes is generally in favor of the computation. As a computing these bytes is generally in favor of the computation. As a
result, it would be better to compute the IV on each party then to result, it would be better to compute the IV on each party then to
send it. send it.
