We explain solving degree-3 equation in detail.

To compress the public-key size is to represent the prime-order group with fewer bits than the size of the embedding field. For instance, the recommended size of the finite field is 2048 bits, and the corresponding size of the prime-order group is 224 bits [2], because the discrete logarithm problem in the finite field is easier than in the general group, namely, the elliptic curve. The index calculus is a relatively efficient algorithm to solve the discrete logarithm problem in finite fields.

Let p = 3 and m be odd. An element of groups G± , #G± = pm ± 3pm + 1, is identified by an element of Fpm without distinction among conjugates. The compression map is as follows: T r6/1 : F(pm )6 → Fpm m m 2 g → g + g p + g (p ) m 3 + g (p ) m 4 + g (p ) m 5 + g (p ) . Since #G+ #G− = Φ6 (pm ), The groups G± are subgroups of T6 (Fpm ). Such subgroups are related to supersingular elliptic curves of embedding degree 6. 4 Construction of Decompression for Trace Maps We propose the decompressible trace representation with additional information.
