In cryptography, XTR is an algorithm for public-key encryption. XTR stands for 'ECSTR', which is an abbreviation for Efficient and Compact Subgroup Trace Representation. It is a method to represent elements of a subgroup of a multiplicative group of a finite field. To do so, it uses the trace over * * * * G * F * ( * * p * * 2 * * * ) * * * {\displaystyle GF(p^{2})} * to represent elements of a subgroup of * * * * G * F * ( * * p * * 6 * * * * ) * * ∗ * * * * * {\displaystyle GF(p^{6})^{*}} * . * From a security point of view, XTR relies on the difficulty of solving Discrete Logarithm related problems in the full multiplicative group of a finite field. Unlike many cryptographic protocols that are based on the generator of the full multiplicative group of a finite field, XTR uses the generator * * * * g * * * {\displaystyle g} * of a relatively small subgroup of some prime order * * * * q * * * {\displaystyle q} * of a subgroup of * * * * G * F * ( * * p * * 6 * * * * ) * * ∗ * * * * * {\displaystyle GF(p^{6})^{*}} * . With the right choice of * * * * q * * * {\displaystyle q} * , computing Discrete Logarithms in the group, generated by * * * * g * * * {\displaystyle g} * , is, in general, as hard as it is in * * * * G * F * ( * * p * * 6 * * * * ) * * ∗ * * * * * {\displaystyle GF(p^{6})^{*}} * and thus cryptographic applications of XTR use * * * * G * F * ( * * p * * 2 * * * ) * * * {\displaystyle GF(p^{2})} * arithmetics while achieving full * * * * G * F * ( * * p * * 6 * * * ) * * * {\displaystyle GF(p^{6})} * security leading to substantial savings both in communication and computational overhead without compromising security. Some other advantages of XTR are its fast key generation, small key sizes and speed. |
