Depending on context, we may consider a reflection a special case, where the translation vector is the zero vector. The combination of a reflection in a line and a translation in a perpendicular direction is a reflection in a parallel line. However, a glide reflection cannot be reduced like that.

These are the two kinds of indirect Euclidean group ... consisting of the reflection on the x axis, followed by translation of one unit parallel to it. In coordinates ... group generated by just a glide reflection is an infinite cyclic group .

Unreferenced date December 2009 In Euclidean geometry , oblique reflections generalize ordinary reflection mathematics reflections by not requiring that reflection be done using perpendicular s. If two points are oblique reflections of each other, they will still stay so under affine transformation s. Consider a plane geometry plane P in the three dimensional Euclidean space . The usual reflection of a point A in space in respect to the plane P is another point B in space, such that the midpoint of the segment AB is in the plane, and AB is perpendicular to the plane. For an oblique reflection , one requires instead of perpendicularity that AB be parallel to a given reference line. Formally, let there be a plane P in the three dimensional space, and a line L in space not parallel to P . To obtain the oblique reflection of a point A in space in respect to the plane P , one draws through A a line parallel to L , and lets the oblique reflection of A be the point B on that line on the other side of the plane such that the midpoint of AB is in P . If the reference line L is perpendicular to the plane, one obtains the usual reflection. For example, consider the plane P to be the xy plane, that is, the plane given by the equation z 0 in Cartesian coordinates . Let the direction of the reference ... reflection of a point x , y , z will then be math left x frac 2za c , y frac 2zb c , z right . math The concept of oblique reflection is easily generalizable to oblique reflection in respect to an affine ... reflection in respect to a k dimensional affine subspace, with a n &minus k dimensional affine subspace serving as a reference.

That is, the same challenge response protocol is used by each side to authenticate the other side. The essential idea of the attack is to trick the target into providing the answer to its own challenge. ref Computer Networks by Andrew S. Tanenbaum , 4th edition, ISBN 0 13 038488 7, pages 787 790. ref Attack The general attack outline is as follows The attacker initiates a connection to a target. The target attempts to authenticate the attacker by sending it a challenge. The attacker opens another connection to the target, and sends the target this challenge as its own. The target responds to the challenge. The attacker sends that response back to the target on the original connection. If the authentication protocol is not carefully designed, the target will accept that response as valid, thereby leaving the attacker with one fully authenticated channel connection the other one is simply abandoned . Solution Some of the most common solutions to this attack are described below The responder sends its identifier within the response so, if it receives a response that has its identifier in it, it can reject it. ref Ross J.
