Komodo is pleased to announce the integration of Dilithium, a quantum-secure digital signature scheme. This new technology provides protection against attacks from quantum computers, ensuring an unparalleled level of security.
While adopting a quantum-secure cryptographic signature scheme would ordinarily be the sole focus of an entire blockchain project— perhaps with its own coin, an ICO, and a dedicated team of developers— the power of Komodo’s technology allowed jl777 to complete the task in just a few days. Now, quantum security is an optional plug-in available to all projects that create a blockchain within the Komodo ecosystem.
A Brief Overview of Digital Signatures
First invented in the late 1970s, digital signatures were a huge breakthrough for all of modern cryptography and computer science. Digital signature schemes implement a form of cryptography known as public key cryptography, also known as asymmetric cryptography.
Whitfield Diffie and Martin Hellman are credited with the coming up with the notion of public key cryptography. Ralph Merkle is also cited for his contributions to the founding of public key cryptography, as well as his creation of the data organization method now known as a Merkle tree.
In short, public key cryptography produces two different “keys”— a private key and a public key. The private key is used to derive the public key. A public key can be shared publicly, as it is impossible to determine the private key from the public key. Anyone can encrypt data using a public key, such that the data can only be decrypted using the corresponding private key.
Digital signature schemes use public key cryptography to securely transfer data electronically. A receiver of encrypted data does not need to know the sender’s private key in order to verify that the message definitely came from the owner of the private key. In addition, ...
