【 摘 要 】

Based on Stanek’s results [1] we know that inmodel with integer rate PGV like compression functions no high speed collision resistant compression functions exist. Thus we try to study more general multiple block ciphers based model of compression functions with rational rate, like 6/5. We show a new upper bound of the rate of collision
