The security evaluation of TOYOCRYPT-HRI and TOYOCRIPT-HSI stream ciphers was presented. A technique for the TOYOCRYPT-HRI was developed based on its algebraic analysis and the employment of time-memory-data trade-off approach. The dimension of the effective secret-key was only 96 bits, although the secret key consisted of 128 bits.
