Timely Authentication in Distributed Systems
Kwok-Yan Lam, Thomas Beth
Keywords : Distributed operating systems, authentication protocols, interprocess communications
Abstract : This paper discusses the use of time in distributed authentication. Our first objective is to give reasons for the provision of authentication protocols whose correctness depends on the correct generation of timestamps. Our second objective is to explain that this proposal is not, at least theoretically, as insecure as it first seems to be. The conclusion of this paper motivated our current effort of designing a secure clock synchronization protocol as a part of our overall goal of building a secure distributed system.
