| Title: | HIGHT Algorithm |
|---|---|
| Description: | HIGHT(HIGh security and light weigHT) algorithm is a block cipher encryption algorithm developed to provide confidentiality in computing environments that demand low power consumption and lightweight, such as RFID(Radio-Frequency Identification) and USN(Ubiquitous Sensor Network), or in mobile environments that require low power consumption and lightweight, such as smartphones and smart cards. Additionally, it is designed with a simple structure that enables it to be used with basic arithmetic operations, XOR, and circular shifts in 8-bit units. This algorithm was designed to consider both safety and efficiency in a very simple structure suitable for limited environments, compared to the former 128-bit encryption algorithm SEED. In December 2010, it became an ISO(International Organization for Standardization) standard. The detailed procedure is described in Hong et al. (2006) <doi:10.1007/11894063_4>. |

HIGHT (HIGh security and light weigHT) is a symmetric key block cipher algorithm designed for use in resource-constrained environments such as embedded systems and wireless sensor networks. Outputs 64-bit ciphertext from 128-bit master key and 64-bit plaintext. This process can be repeated multiple times.
hight_dec(C, MK, mode, IV = NULL, output = "int")hight_dec(C, MK, mode, IV = NULL, output = "int")
C |
Encrypted plaintext by HIGHT. |
MK |
Master Key. This is used to encrypt other keys that are used to encrypt and decrypt data. This should be typically kept secret and is only accessible to authorized users who need to use it for encryption and decryption operations. It should have a length of 16 and must have a value from 0 to 255. |
mode |
Please select one from 'ecb'(Electric CodeBook mode),'cfb'(Cipher FeedBack mode),'cbc'(Cipher Block Chaining mode),'ofb'(Output FeedBack mode). |
IV |
Initialization Vector. The IV is usually generated randomly and is different for each encryption operation. It is combined with the encryption key to produce a unique key for each encryption operation. Its length must be equal to 8, which is a unit of cryptographic block, and the value range must also have a value from 0 to 255. This parameter will be ignored in ECB mode. |
output |
Support 'hex'(e.g. '0x66') string or 'int'(e.g. 102) for output format. |
Returns a numeric vector decrypted by the HIGHT algorithm.
