To enhance the security and reliability of the widely-used stream ciphers, a 2-D and a 3-D mesh-knight Algorithm Based Fault Tolerant (ABFT) schemes for stream ciphers are developed which can be universally applied to RC4 and other stream ciphers. Based on the ready-made arithmetic unit in stream ciphers, the proposed 2-D ABFT scheme is able to detect and correct any simple error, and the 3-D mesh-knight...
Growth condition of p-chloroaniline (p-CA) degrading Bacillus licheniformis named strain ycsd02 which was isolated from rhizosphere soil in phragmites wetland and stored in our labrary was studied. The result showed that the optimal culture temperature, culture pH value and dissolved oxygen for satisfactory cells growth were about 37degC, pH7.2 and 4 mgldrL-1 in LB liquid medium. Growth of strain...
