RMAC – A LIGHTWEIGHT AUTHENTICATION PROTOCOL FOR HIGHLY CONSTRAINED IOT DEVICESijcisjournal
Nowadays, highly constrained IoT devices have earned an important place in our everyday lives. These devices mainly comprise RFID (Radio-Frequency Identification) or WSN (Wireless Sensor Networks) components. Their adoption is growing in areas where data security or privacy or both must be guaranteed. Therefore, it is necessary to develop appropriate security solutions for these systems. Many papers have proposed solutions for encryption or authentication. But it turns out that sometimes the proposal has security flaw or is ill-suited for the constrained IoT devices (which has very limited processing and storage capacities).In this paper, we introduce a new authentication protocol inspired by Mirror-Mac (MM) which is a generic construction of authentication protocol proposed by Mol et al. Our proposal named RMAC is well suited for highly constrained IoT devices since its implementation uses simple and lightweight algorithms. We also prove that RMAC is at least as secure as the MM protocol and thus secure against man-in-the-middle attacks.

Transport mode and tunnel mode are the two modes of IPSec. Transport mode provides protection only for upper layer protocols, while tunnel mode protects the entire IP packet. Some consider IPSec as a replacement for SSL since it provides similar security functions at the network layer instead of the application layer. However, others argue SSL provides additional functionality like authentication.
The AH and ESP protocols provide authentication and encryption respectively in IPSec. While AH provides integrity and data origin authentication, the same functions can also be provided by ESP, so some argue AH is not strictly necessary.
PGP uses the cipher feedback mode instead of cipher block chaining used in most symmetric encryption to provide asynchronous encryption/decryption and allow encrypting data a block
