[edit] Some significance to 40 bytes?

The article mentions if q < 2^160, then the signature is less than 40 bytes. This is obviously true, but is there any special significance to 40 bytes?

I believe that it means that even when the group order is large, the signature is small. For instance, using a 1024-bit prime field (128 bytes), the signature would still be 40 bytes, with a security level of 80 bits. For the same security level, DSA signatures would have 40 bytes, too.

[edit] Patent expired?

The article says: "It is covered by U.S. Patent 4,995,082 , which expires in February 2008." February 2008 is now. However, the priority date of the patent is February 24th 1989 (according to the link); why is it that the patent does not expire in 2009? —Preceding unsigned comment added by 202.246.252.97 (talk) 05:18, 29 February 2008 (UTC)
