摘要： A server for performing an operation on a homomorphic ciphertext is configured to: receive a first homomorphic ciphertext, a public key, and a first hierarchical Galois key set from a client device; in response to a request for generating a second hierarchical Galois key set for performing a rotation operation on the first homomorphic ciphertext of the client device, generate the second hierarchical Galois key set, based on the received public key and hierarchical Galois key set; and when a decomposition operation for a first Galois key included in the second hierarchical Galois key set overlaps with a decomposition operation for a second Galois key, first perform the decomposition operation for the first Galois key, and then substitute the decomposition operation for the second Galois key with a result of the decomposition operation for the first Galois key.

摘要： A processor-implemented method with homomorphic encryption includes: receiving a first ciphertext corresponding to a first modulus; generating a second ciphertext corresponding to a second modulus by performing modulus raising on the first ciphertext; and performing bootstrapping by encoding the second ciphertext using a commutative property and an associative property of operations included in a rotation operation.

摘要： Disclosed is an electronic apparatus. The electronic apparatus includes a memory storing a composite function in which at least two polynomials are composed and a processor configured to, based on a comparison operation command being received for a plurality of homomorphic ciphertexts, perform operation by reflecting the plurality of homomorphic ciphertexts to the composite function, and obtain a comparison result of the plurality of homomorphic ciphertexts based on the operation result, each of the at least two polynomials may output a value in a preset range for a value in a preset domain, and a domain of one of the at least two polynomials may be determined based on a range of a previous polynomial.

摘要： A processor-implemented encryption method using homomorphic encryption includes: receiving data; generating a ciphertext by encrypting the received data; determining a coefficient of an approximating polynomial for performing a modular reduction on a modulus corresponding to the ciphertext, based on an error between the approximating polynomial and a modular reduction function; and performing bootstrapping on the ciphertext by performing the modular reduction based on the determined coefficient of the approximating polynomial.

摘要： Provided is an electromyogram (EMG) signal-based user authentication apparatus and method. The apparatus includes an EMG signal receiver configured to receive an EMG signal measured using an EMG sensor, a pre-processor configured to remove a partial signal from the received EMG signal according to a preset frequency band, and a controller configured to authenticate a user by comparing a pre-stored EMG signal with the EMG signal in which the partial signal has been removed.

摘要： Light is irradiated to a finger of a subject and received from the finger of the subject to extract a pulse wave signal, generates an optimized pulse wave signal in a desired type by sampling the extracted pulse wave signal according to a predetermined sampling condition and normalizes the generated pulse wave signal, the entire segment of the normalized pulse signal is divided into a plurality of window segments to detect a pulse wave amplitude value with respect to a pulse wave signal for each window, a first eigenvector for each subject corresponding to a pulse wave amplitude value of the entire window segment is extracted by using a linear discriminant analysis and then the first eigenvector per subject is compared with a threshold, determines distribution of eigenvectors for each subject compared to the threshold and thus a characteristic of the corresponding subject is diagnosed.

摘要： Disclosed herein is a cell death-inducing peptide that rapidly acts. The peptide is derived from Noxa protein and comprises 16 amino acid residues including MTD. The peptide is designated extended MTD (eMTD) because it contains the 10-mer MTD. eMTD rapidly exhibits potent necrotic cell death in various cell lines and, as such, can be applied to the treatment of various diseases including cancer when used in conjugation with peptides or materials for targeting specific cells.

摘要： Disclosed is an electronic device for performing code-based encryption supporting integrity verification of a message and an operating method thereof. When a data transmission side encrypts a message through code-based encryption and transmits the encrypted message to a data reception apparatus, the data transmission side is allowed to use a hash value generated based on a part of the message as an error in code-based encryption to support the data reception apparatus to verify an integrity of a received message by using the hash value.
