- What are digital signatures?
A digital signature is an electronic fingerprint to securely associate a digitally recorded document like medical records or a financial transaction, to a signer. When you, the server, digitally sign a document, you add a one-way hash (encryption) of the message content using your public and private key pair.
- What is a quantum attack?
Common public key cryptographic protocols such as RSA and ECDSA used to secure the internet and financial transactions are susceptible to attack by the development of a sufficiently large quantum computer. This would allow the attacker to forge documents without being detected.
- What is quantum cryptography?
In the history of cryptography, quantum cryptography is a new and important chapter. It is a technology in use today to ensure the confidentiality of information transmitted between two parties, usually called Alice and Bob, by exploiting the quantum behaviour of particles such as photons.
- What does post-quantum crypto mean?
Post-quantum cryptography (sometimes referred to as quantum-proof, quantum-safe or quantum-resistant) refers to cryptographic algorithms (usually public-key algorithms) that are thought to be secure against an attack by a quantum computer. The National Institute of Standards and Technology has solicited a call to standardize post quantum cryptography .
