Analysis of sponge function based authenticated encryption schemes
Lekshmi Krishnan, M. Sindhu, Chungath Srinivasan · 2017
Today's modern communication systems are to be protected from many security risks. Confidential messages sent over an insecure channel should be ensured integrity along with privacy. Authenticated encryption is such a scheme which provides both privacy and integrity simultaneously. Privacy is achieved by means of encryption and authentication using a Message Authentication Code (MAC). For resource-constrained devices, lightweight authenticated encryption schemes are to be devised. Sponge function is an ideal candidate for designing these lightweight schemes. In this paper, a literature survey is made on sponge function based authenticated encryption schemes, their designs and security details. Finally, a comparison of all these schemes is performed.
