摘要： A method of operating a system on chip (SoC) includes converting plain data into cipher data by using an encryption key and transmitting the cipher data directly to a memory controller which controls an operation of a non-volatile memory. The encryption key may be output by a one-time programmable (OTP) memory.

摘要： Provided is a cryptographic device implementing an S-Box of an encryption algorithm using a many-to-one binary function. The cryptographic device includes: arrays of first logic gates including I first logic gates which each receive 2 bits of an input signal; 2N second logic gates which each receive corresponding J bits from among I bits output from the arrays of the first logic gates; and L third logic gates which each receive K bits from among 2N bits output from the second logic gates, wherein there is a many-to-one correspondence between the N bits of the input signal and the K bits input to each of the third logic gates, and wherein the N, I, J, K, and L are positive integers. Because a signal output from each array includes only one active bit, current is always consumed constantly to prevent internal data from leaking out to a hacker.

摘要： A password system includes a user interface, a password generating unit, and a password checking unit. The password generating unit generates a password including multiple frames, generates an integrity check code associated with the generated password, and scrambles the generated password and provides the scrambled password to the user interface. The password checking unit stores the integrity check code, frame number information and scramble information which are provided from the password generating unit, descrambles a scrambled password that is input from the user interface based on the stored scramble information, and authenticates the user interface by comparing an integrity check code generated from the descrambled password and the stored integrity check code.
