Abstract: Cryptographic algorithms become more complex and “heavyweight” every year. This is completely correct from the viewpoint of security. But at the same time such growth increases resource requirements of the algorithms and the complexity of their implementation. This also essentially increases expenses of energy required to perform cryptographic procedures. In this paper we review applications of cryptographic algorithms in routing protocols. Also we analyze the possibilities of use of a lightweight block cipher as a cryptographic kernel to mount various types of cryptographic algorithms which do not require significant resources together over it. We propose to enlarge the set of cryptographic algorithms required to be implemented within IPsec protocol and to include lightweight encryption and authentication algorithms into the set. Implementation of lightweight algorithms to apply in IPsec and related network protocols allows to provide adequate moderate security level in various applications where it is not required to use heavy and strong cryptography; it also allows to save energy and reduce the cost of implementation.

Keywords: Lightweight cryptography, KATAN, block cipher, hash function, routing protocol, RIPv2, IPsec.
