An integrated one-chip security module for a smart energy security threat response included in an intelligent smart meter constituting a smart energy system, comprising:
- a first core unit collecting measured data generated in an operation process of the smart energy system and stores the measured data in a security memory;
- and
- a second core unit encrypting the measured data stored in the security memory and transmitting the encrypted data to an external device,
- wherein the second core unit includes:
- a communication unit communicating with an external interface to transmit and receive data;
- an encryption unit accessing the security memory to encrypt the measured data stored in the security memory and transferring the encrypted specific data to the communication unit;
- and
- an operation unit controlling a data processing process generated through the second core unit, and
- wherein the encryption unit is withholding a transmission process of the measured data until the measured data collected in the security memory are accumulated and stored by a predetermined number, setting variable data representing a feature of an accumulated and stored data group when it is confirmed that the measured data have been accumulated and stored by the predetermined number, and encrypting the measured data on the basis of the set variable data.
The integrated one-chip security module for a smart energy security threat response of claim UM, wherein the setting of the variable data representing the feature of the accumulated and stored data group
- calculates the number of measured data representing the same measured value among a plurality of accumulated and stored measured data and sets measured data representing the same measured value most as the variable data, when it is confirmed that the measured data have been accumulated and stored by the predetermined number, and
- calculates an average value of the plurality of accumulated and stored measured data and sets the calculated average value as the variable data, converts modified data in which the set variable data and the respective measured data are combined with each other into hash values using a hash function, and transfers the converted hash values to the communication unit, when it is confirmed that all of the plurality of accumulated and stored measured data represent different measured values.
