Disclosed are a calculation device for encryption using a public key and an encryption method thereof. The present method comprises: a step for setting a secret key, and generating a public key using the secret key and an error extracted from a discrete Gaussian distribution or a distribution that is within a short statistical distance thereto; and a step for applying the public key to a message, and then performing a rounding process to encrypt the message. Accordingly, encryption efficiency can be enhanced.

A programmable logic device verifies that configuration data permissibly programs the programmable logic device. The programmable logic device includes a programmable fabric having partitions to be programmed by the configuration data, a secure device manager that may generate masks based on the configuration data, and a local sector manager. The masks determine that the configuration data is configured to permissibly program the permitted partitions or that the permitted partitions have been permissibly programmed. The local sector manager applies the masks to generate an interleaved result, compares the interleaved result to an expected result, and sends an indication that the configuration data is configured to permissibly program the permitted partitions or permissibly programmed the permitted partitions in response to determining that the interleaved result is the expected result, or sends an alert to stop programming in response to determining that the interleaved result is not the expected result.

The disclosure relates to improvements in secure channel establishment. In some aspects, the techniques described herein relate to a method including: issuing, by a client device to a server, a request to establish a secure connection; receiving, by the client device, a response to the request to establish a secure connection from the server, the response including a digital certificate associated with a public key stored by the server, the public key used to establish a symmetric key; validating, by the client device, the digital certificate; and computing, by the client device, a shared secret using the public key stored by the server and a private key generated by the client device.

A communication device may receive a specific signal from a first external device; display a first instruction screen; in a case where it is instructed that the target process is to be executed in a situation where the first instruction screen is displayed, send a public key to the first external device, wherein in a case where it is not instructed that the target process is to be executed in the situation where the first instruction screen is displayed, the public key is not sent; after the public key has been sent to the first external device, receive an authentication request from the first external device; send an authentication response to the first external device; receive connection information from the first external device; and establish, by using the connection information, a wireless connection between the communication device and a second external device.
