The present disclosure relates to methods, devices, and systems for generating a signature of a message by a first device based on a secret key and a public key. The method includes generating a first parameter based on a first multiplication operation on the secret key and a first random number. The method further includes generating a first electronic signature based on the first parameter and the public key. The method further includes generating a second parameter based on the first random number, a second random number, and the message. The method further includes generating a second electronic signature based on the first parameter, the second parameter, the second random number, and the first electronic signature. The method further includes outputting, to a second device, the message, the first electronic signature, and the second electronic signature.

Encryption device and authentication method and signature generating method of system including the same

An operation method of a security device which includes a plurality of physical unclonable function (PUF) cells includes selecting a target PUF cell of the plurality of PUF cells, selecting at least two reference PUF cells of the plurality of PUF cells based on a sorted list, reading a plurality of sensing data from the target PUF cell and the at least two reference PUF cells, and determining a target bit corresponding to the target PUF cell based on the plurality of sensing data to output the determined target bit.

Security device including physical unclonable function cells and operation method thereof

A system-on-chip includes a magnetic random access memory and a security interface. The magnetic random access memory includes a plurality of memory areas, each of the plurality of memory areas having a different security level. The security interface circuitry configured to: identify a memory area from among the plurality of memory areas based on a received memory address associated with a received memory command; determine a security level associated with the identified memory area; and perform a memory operation on received data based on the received memory command and the determined security level.

System-on-chips and operation methods thereof

A method for setting a password for operating an application of a user device is provided. The method includes requesting the user device to input a password of the application, and requesting the user device to select device binding information of the user device to associate with the password. The device binding information is obtained from one or more of contact information, a photo, an e-mail, a file, or an address.

User device, method for setting password thereof, and operating method for setting and verifying password thereof
