I Want to Forget: Fine-Grained Encryption with Full Forward Secrecy in the Distributed Setting
puncturable encryption forward secrecy distributed setting
2019/8/14
Managing sensitive data in highly-distributed environments is gaining a lot of attention recently. Often, once data is presented to such environments, this data is persistent there. Being able to "for...
k-root-n: An efficient O(√n) algorithm for avoiding short term double spending in Distributed Ledger Technologies such as Blockchain
Blockchain bitcoin distributed ledger technology
2019/7/17
Blockchains such as bitcoin rely on reaching global consensus for the distributed ledger, and suffer from a well know scalability problem. We propose an algorithm which can avoid double spending in th...
