GENERATION OF SESSION PARAMETERS FOR EL GAMAL-LIKE PROTOCOLS

摘要

The public key, either short term "session" key or long term key, is generat ed by combining a pair of components. A first component is obtained by utilizing a n integer with a relatively low Hamming weight as an exponent to facilitate exponentiation. The second component is a precomputed secret value that is of the form resulting from the exponentiation of the generator of the group element by an integer that has the requisite Hamming weight. The two components are combined to provide the public key an d the two exponents combined to provide the corresponding private key.
