3 days ago · Lamport Signatures. Lamport signatures were invented in 1979 by Leslie Lamport—though they are insecure without modern cryptographic hash functions, which did not exist until the 1990s—and are one of the few cryptographic objects from that era that endure to this day.
4 days ago · Leslie B. Lamport's profound impact on distributed systems is exemplified through his development of the Paxos algorithm. This algorithm addresses consensus-related challenges in distributed systems by ensuring that nodes reach agreement even in the presence of failures or delays.
2 days ago · Paxos is a family of protocols developed by Leslie Lamport for achieving consensus in distributed systems despite network delays, node failures, and message losses. Paxos ensures that all nodes agree on a single value even if some nodes fail. The protocol involves proposers, acceptors, and learners.
5 days ago · Abstract. To facilitate dynamic spectrum sharing, the FCC has designated certified SAS administrators to implement their own spectrum access systems (SASs) that manage the shared spectrum usage in the novel CBRS band. As a premise, different SAS servers must conduct periodic inter-SAS coordination to synchronize service states and ...

5 days ago · Unfortunately, known constructions work only with non-standard signature schemes and require non-existing secure hardware, making them impractical. In this paper, we construct single-use delegatable ECDSA signatures based on commodity smartphones with hardware-backed keystores.
4 days ago · The Byzantine Generals’ Problem was first introduced by Leslie Lamport, Robert Shostak, and Marshall Pease in their 1982 paper, “The Byzantine Generals Problem.” These computer scientists used the metaphor of Byzantine generals to describe the issue of achieving consensus in distributed systems.
