Abstract: The difficulty of computing discrete logarithms known to be "short" is examined, motivated by recent practical interest in using Diffie-Hellman key agreement with short exponents (e.g. over Zp with 160-bit exponents and 1024-bit primes p). A new divide-and-conquer algorithm for discrete logarithms is presented, combining Pollard's lambda method with a partial Pohlig-Hellman decomposition. For random DiffieHellman primes p, examination reveals this partial decomposition itself allows... (Update)

...Z p , and elements g x 2 Z p and g y 2 Z p , find g xy 2 Z p . These two problems hold their properties in a prime order subgroup[30, 28]. We assume that all numerical operations of the protocol are on the cyclic group where it is hard to solve these problems. We consider the...

...the order of J K L . 3. 3 Attacks Based on Composite Order Subgroups The attacker can exploit subgroups that do not have large prime order [51]. This is best illustrated by an example. Suppose Alice and Bob choose a prime M U R , where q is prime, and a generator of order...
