A server for performing an operation on a homomorphic ciphertext according to an embodiment of the present disclosure may be 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. In addition, the second hierarchical Galois key set may be sequentially generated according to a predetermined generation order.
摘要:
In a client-server model for generating a rotation operation key in fully homomorphic encryption, a client transmits a public key and a hierarchical Galois key generated using a secret key to a server, and the server performs a rotation operation on the public key using the hierarchical Galois key to directly generate one or more rotation operation keys, so that the server may generate a rotation operation key if necessary while computational burden and communication cost of the client are reduced.

A novel use of P 44 as a marker for predicting or diagnosing anaplasmosis is disclosed. A diagnostic composition for anaplasmosis containing a P 44 gene, a primer set or probe for detecting Anaplasma phagocytophilum, a kit for diagnosing anaplasmosis, and a method for providing information to diagnose infection with Anaplasma phagocytophilum are also disclosed. P 44 , which is a novel biomarker for diagnosing anaplasmosis, is a multi-copy gene and exists in a large number of copies in the Anaplasma phagocytophilum genome, thus having the effect of detecting Anaplasma phagocytophilum infection at high sensitivity using only a small amount of DNA compared to conventional diagnostic marker genes. In addition, the primer set or probe for detecting and amplifying P 44 is capable of providing rapid and easy detection of anaplasmosis with high specificity and sensitivity, making it appropriate for early detection of anaplasmosis.
