Secure signatures based on post-quantum computing
A recently granted patent (Publication Number: US11750400B2) describes a method performed by a computing system for generating a public key. The method involves generating a plurality of one-time signature (OTS) key pairs, each consisting of an OTS private key and an OTS public key. For each OTS key pair, a hash of the OTS public key is generated. Additionally, a hash is generated from a seed, which is a random number that is not an OTS private key or an OTS public key. The method further involves generating a hash of a hash derived from the OTS public key of each OTS key pair and a previously generated hash. The public key is designated as the generated hash.
The patent also describes a method for generating a public key using a combination of OTS key pairs. The method involves generating a first OTS key pair, a first tailback OTS key pair, and a hash of the first tailback OTS public key and the first OTS public key. The first OTS private key is used to sign a first message, while the first tailback OTS private key is used to sign a hash of a hash of a second tailback OTS public key and a hash of a second OTS public key. The OTS key pairs can be based on either a Lamport OTS scheme or a Winternitz-based OTS scheme.
The patent also covers methods for generating a signature for content based on a public key, generating a signature for data, generating a signature based on a chain of hashes, and regenerating a public key based on multiple OTS key pairs. These methods involve various steps such as adding OTS signatures, generating metadata, and performing hash operations.
The patent further describes a computing system for generating a public key, regenerating a public key, and generating signatures. The system includes one or more computer-readable storage mediums storing computer-executable instructions and one or more processors for executing these instructions.
Overall, the patent presents methods and systems for generating public keys and signatures using OTS key pairs and hash operations. These techniques can be applied in various computing systems and have potential applications in secure communication and data integrity verification.
