origin of SHA 224 initial hash values

I'm having trouble pinpointing the origin of the initial hash values for SHA 224 and, for that matter, 128. These values are defined as hex representations of cube roots of primes for sha-1 of lengths 256, 384 and 512, but I can't find where they were obtained for the shorter lengths. Thanks

safety of Pohlig-Hellman with a common modulus?

Is it safe to use Pohlig-Hellman encryption with a common modulus? That is, I want various parties to have their own exponents, but share the same prime modulus. In my application, a chosen plaintext attack will be possible. (I know that RSA with common modulus is not safe.)
