"Perfect" randomness suggests "true" randomness to me. In particular, the restriction to "efficient" statistical tests does not seem implied. "Cryptographically strong" is well defined and is actually descriptive of what is needed, but tends to be a mouthful to say and a bother to type. "Unpredictable" is fine, although explinations are sometimes needed. "Secure" has connotations that may color discussions. So all in all, I prefer "unpredictable" followed by "cryptographically strong", and the latter in cases where clarity is more important than convenience. --Ken Pizzini
