15.6.2 Reference

Prev Up Next Page 791 of 800 Search internet

A sequence of around 30 bytes which uniquely identify a Logiweb page. The reference consists of a one byte protocol version number, a 20 byte RIPEMD-160 hash key, and a timestamp.

Having a trusted reference of a page together with an untrusted vector of the same page, one can use RIPEMD-160 to verify the authenticity of the vector. For that reason, one can retrieve pages from untrusted repositories over untrusted connections as long as one knows the reference of the page.
