ITUbee is the lightweight encryption algorithm that was proposed by the second International Symposium on lightweight encryption security and privacy in 2013. It is based on the Feistel network. We optimized S-box, round function and round constant addition. The optimized round constant is the variable which is converted from the related round number i. There is no need to allocate area resource for it. The experimental results show that the throughput of the optimized ITUbee algorithm reaches 364.695 Mb/s. The area is reduced to 10650 Slices. We studied and implemented the masking ITUbee algorithm to resist power analysis attack. The implemented performance is also compared. The area of the masking ITUbee is increased by about 4%. The clock frequency is raised from 100.291 MHz to 102.396 MHz, throughput is increased from 364.695 Mb/s to 372.349 Mb/s.
