A commercial alternative to QKD: filling USB sticks and hard disks with random bits (completed)

Quantum key distribution (QKD) offers unconditional security according to the laws of quantum physics. A QKD system enables its users to securely set up symmetric keys for encryption by sending quantum signals, either over optical fibres or over free-space. In current commercial QKD systems, these symmetric keys are consumed in classical secure communications protocols like … full description “A commercial alternative to QKD: filling USB sticks and hard disks with random bits (completed)”

Developing a Steganographic Wallet for Cryptocurrencies (available)

Steganography is a well-known mechanism that has been used for centuries (with different levels of sophistication) to avoid censorship and enable secret communications. Cryptocurrency wallets are normally protected by different levels of encryption and can even be stored into hardware wallets with different levels of security. Carrying one of this wallets can be problematic in … full description “Developing a Steganographic Wallet for Cryptocurrencies (available)”
