Competitive Advantages
- Less memory is required for the signature and communication, as it does not require the signer to store and send the public key.
- Meets the NIST post-quantum cryptography standard with faster and memory-efficient processing on the signer’s side.
- The algorithm does not require any repetition of the signing algorithm. Also, due to the one-time nature of the signing scheme, it does not need to compute a commitment in signing.
Summary
Our researchers have developed a system and method for a new signature scheme for authentication in IoT devices. This novel lightweight algorithm meets the resource-constraining requirements of processing, memory, bandwidth, and battery life for IoT devices like implantable medical devices. The new scheme is LPQS and is based on a one-time lattice-based signature with a distributed verification process via semi-honest verification servers. This approach enables resource-limited signers to compute signatures without costly lattice, only with a low memory expansion/footprint and compact signature sizes. This new scheme also meets the NIST standard for post-quantum cryptography, ensuring long-term security in the coming age of quantum computing. Compared to the related counterparts in terms of performance, the benefit of this algorithm is significant; it reduces the signer's memory requirement and is also faster and memory efficient on the signer’s side. The signature size in the numerical figures is 138 bits in this scheme compared to 1.2 kb in other comparable algorithms.
