The sublanguage provides useful information-flow control mechanisms including dynamic security lattices, run-time code privileges and declassification all without modifying the base language.
The security of lattice-based cryptographic schemes can be measured by the root Hermite factor.
They are organized in topical sections named: public-key cryptography, foundation, symmetric cipher, security proof, lattice-based cryptography and number theory, hash function, cryptographic protocol, and implementation issues.
To obtain various security levels, we take four lattice dimension parameters n=2048,4096,8192 and 16384 (as the lattice dimension is larger, the security becomes higher).
The papers are organized in topical sections on key exchange, secure computation, public-key encryption, network security, traitor tracing, authentication and anonymity, hash fundtions, lattices, and side-channel attacks.
Back in September, a private equity group was blocked from purchasing Lattice Semiconductor due to potential security risks.

Going back to at least to September 2016, Google has reportedly filed more than 20 patents for blockchain-related technology, including one in 2018 for using a "lattice" of interoperating blockchains to increase security.
According to the state-of-the-art security analysis of Chen and Nguyen [5] for lattice-based cryptographic schemes, a root Hermite factor smaller than δ=1.0050 is estimated to have more than 80-bit security level with an enough margin.
To our best knowledge, no lattice based FIBS schemes were known before, and the existing security model of FIBS schemes is not correct indeed.
