LED (Light Encryption Device) block cipher, one of lightweight block ciphers, is very compact in hardware. The conventional scan-based side-channel attack method on the LED would not retrieve the secret key if the scan chain length in the LED LSI is about 30,000 bits or more. In this paper, an improved scan-based attack method on the LED block cipher independent of scan structure is proposed. Experimental results show that our proposed method successfully retrieves its 64-bit secret key using 36 plaintexts on average if the scan chain is only connected to the LED block cipher. These experimental results also show the key is successfully retrieved even if the scan chain includes additional 130,000 1-bit registers. |
