암호화에서 그럴듯한 부인이란?

암호화 에서 거부 가능한 암호화 는 공격자가 암호화된 메시지의 존재를 증명할 수 없다는 의미에서 암호화된 파일 또는 메시지의 존재 자체를 거부 할 수 있는 스테가노그래피 기술 을 설명하는 데 사용될 수 있습니다. 이 경우 시스템을 "완전히 감지할 수 없음"(FUD)이라고 합니다.

MaruTukku , FreeOTFE 및 (훨씬 적은 정도) TrueCrypt 및 VeraCrypt 와 같은 일부 시스템은 암호화된 데이터를 중첩합니다. 암호화된 데이터의 소유자는 데이터에서 특정 정보를 해독하기 위해 하나 이상의 키를 공개한 다음 더 많은 키가 존재한다는 사실을 거부할 수 있습니다. 이 진술은 관련된 모든 암호화 키에 대한 지식 없이는 반증할 수 없습니다. 명백히 암호화된 데이터 내에 "숨겨진" 데이터의 존재는 존재를 입증할 수 없다는 의미에서 부정 할 수 있습니다.

2줄요약
- 히든볼륨 만들고 윈도우 파티션도 암호화해라.
- 오픈볼륨 암호키를 제공하고 히든볼륨 암호키는 없다고 주장하고 윈도우 파티션마저 잠겨있다면(도킹기록 확인불가) 수사기관은 히든볼륨이 존재함을 증명할 수 없다.

How Does Bitcoin Work?

Bitcoin is built on a distributed digital record called a blockchain. As the name implies, blockchain is a linked body of data, made up of units called blocks that contain information about each and every transaction, including date and time, total value, buyer and seller, and a unique identifying code for each exchange. Entries are strung together in chronological order, creating a digital chain of blocks. “Once a block is added to the blockchain, it becomes accessible to anyone who wishes to view it, acting as a public ledger of cryptocurrency transactions,” says Stacey Harris, consultant for Pelicoin, a network of cryptocurrency ATMs. Blockchain is decentralized, which means it’s not controlled by any one organization. “It’s like a Google Doc that anyone can work on,” says Buchi Okoro, CEO and co-founder of African cryptocurrency exchange Quidax. “Nobody owns it, but anyone who has a link can contribute to it. And as different people update it, your copy also gets updated.”
