A processor-based method comprising: bootstrapping a first ciphertext that is a fully- homomorphic encryption of a plaintext, the plaintext being representable as a vector of coefficients of a polynomial, the bootstrapping comprising: obtaining, from the first ciphertext, an encryption of data indicative of one or more coefficients of the plaintext; based on a bootstrapping key, performing Torus-fully-homomorphic-encryption (TFHE) bootstrappings on the obtained encryption of data, the bootstrappings resulting in one or more bootstrap outputs; deriving, from the bootstrap outputs, a series of one or more encrypted values, each value of the series being based on a coefficient of a respective term of a polynomial; and creating, from, at least, a key-switching-key and the derived series of encrypted values, data indicative of a ring-based or module-based ciphertext, resulting in a second ciphertext that is an encryption, with reduced noise, of the data indicative of one or more coefficients of the plaintext.

A multi-system-on-chip (mSoC) can comprise a substrate with multiple chiplet positions, a main chiplet located on the substrate, and one or more secondary chiplets also located on the substrate. The main chiplet performs a self-identification process before the mSoC boots. The main chiplet then powers up and controls the boot process for the one or more secondary chiplets to identify the chiplet configuration on the mSoC. The main chiplet and each of the one or more secondary chiplets include multiple interfaces with the substrate and a communication mechanism for executing the boot process.

The present invention relates to a method for performing an equality checking of a first character and a second character in a fully homomorphic encryption scheme wherein programmable bootstrapping is used, at least one of said first and said second character being encrypted, said first and second character each represented as a plurality of chunks. The method comprises: o checking chunk-by-chunk the equality of the first character with the second character by determining a difference between corresponding chunks, and o using the difference as input for a lookup table operation performed through the programmable bootstrap operation, said lookup table returning a first predetermined value if the difference equals zero and returning a second predetermined value different from the first predetermined value otherwise, wherein a lookup table result for a second or further chunk is determined based on the difference between corresponding current chunks and on a lookup table result for the preceding chunk, and wherein a lookup table result for the last chunk yields an equality result for the pair of characters formed by said first and second character.

Some embodiments are directed to a computer-implemented method (1200) of performing a computation on LWE-encrypted values. The invention relates to the TFHE setting in which the encryption supports a programmable bootstrapping operation that evaluates an LWE decryption in an exponent of a GLWE-encrypted monomial. In this setting, a LWE-encrypted product value is computed based on one or more LWE-encrypted input values by applying a cryptographic key switching operation to convert the LWE-encrypted input values to GLWE-encrypted polynomials, wherein a coefficient of an polynomial is a linear combination of the set of input values; applying an encrypted polynomial multiplication in the GLWE domain, and applying a cryptographic sample extraction operation to the resulting GLWE-encrypted polynomial to obtain the LWE-encrypted product value as an encryption of one of its coefficients.

The disclosed systems and methods may launch a first node of a multi-node cluster from an attached storage medium, such as a USB driver, into a launcher OS. The launcher OS may initiate PXE and file sharing services on the first node. The disclosed features may copy one or more software packages for a target OS from the attached storage medium to a persistent storage device of the first node. The method may also include a PXE booting one or more other nodes of the multi-node cluster into the bootstrap OS and connecting one or more of the other nodes to the first node via a high speed switch. One or more software packages including software for the target OS are copied from the persistent storage device to at least one of the one or more other nodes via the high speed switch.

Methods and systems for performing efficient privacy-preserving machine learning (or other computationally intensive private computing operations) based on homomorphic encryption are disclosed. Two computer systems can collectively perform these methods on behalf of a client computer using threshold leveled homomorphic encryption (LHE) or fully homomorphic encryption (FHE), e.g., using the Cheon-Kim-Kim-Song cryptosystem. For example, two computer systems could privately evaluate a client's encrypted inputs using a machine learning model and return an encrypted output to the client, preserving the privacy of the client's data. Methods according to embodiments include efficient bootstrapping methods, ciphertext packing methods, encryption parameter optimization methods, and methods for privately fine-tuning machine learning models using low rank adaptation (LoRA). Embodiments improve the speed and efficiency of private HE-based computation, which are often several orders of magnitude slower than non-private computation.

A system for fully homomorphic encryption (FHE) inference includes: a plurality of server modules; an interconnect operatively coupled to the modules and configured to distribute session-initialization data for a large-language-model session; a first plurality of application-specific integrated circuits (ASICs) on one or more of the modules, each configured to perform bootstrapping on ciphertexts during an initiation phase; and a second plurality of ASICs on the modules comprising: bootstrapping circuitry configured to store auxiliary data used for bootstrapping and to perform the bootstrapping operations on the ciphertexts; processing circuitry configured to perform homomorphic arithmetic operations other than bootstrapping; and support circuitry configured to perform functions that support the bootstrapping and processing circuitry.

A multi-party system comprising a garbler and an evaluator for interactively executing homomorphic SIMD operations using garbled circuits. The garbler and evaluator may each store a unique share of a shared secret key, a ciphertext, and a shared public key. The garbler and evaluator may each partially decrypt the ciphertext using its key share to generate a unique data share. The garbler may linearize and reduce the size of the unique garbler data share. The garbler may send to the evaluator a garbled circuit, a garbling of the linear unique garbled data share, and garbled potential wires for the evaluator to garble its linear unique evaluator data share by oblivious transfer. The evaluator may evaluate the garbled circuit to execute a SIMD program to combine, in parallel, multiple indices of the linear garbler and evaluator unique data shares to efficiently generate an encrypted result of the garbled circuit.

This invention discloses a metadata-driven method and system for constructing a large language model intelligent agent through bootstrapping, relating to the field of artificial intelligence technology. The method includes the following steps: collecting natural language requirements generated from business scenarios and organizing these requirements into a unified expression format; generating readable metadata description content within this unified expression format; performing field splitting and role attribution around the metadata description content; constructing data type definition metadata within the unified expression format; and embedding prompt words into the data type definition metadata to generate content. This invention achieves progressive generation from natural language to data types, rules, and intelligent agent definitions through unified metadata expression, supporting dynamic construction and automatic loading at runtime, reducing manual intervention, and improving automation. Simultaneously, new metadata is generated during runtime and fed back into the generation chain, forming a continuous bootstrapping closed loop, enhancing structural consistency and version evolution controllability.
