WebNov 22, 2013 · TLSH -- A Locality Sensitive Hash. Abstract: Cryptographic hashes such as MD5 and SHA-1 are used for many data mining and security applications -- they are used as an identifier for files and documents. However, if a single byte of a file is changed, then cryptographic hashes result in a completely different hash value.

One of the easiest ways to construct an LSH family is by bit sampling. This approach works for the Hamming distance over d-dimensional vectors . Here, the family of hash functions is simply the family of all the projections of points on one of the coordinates, i.e., , where is the th coordinate of . A random function from simply selects a random bit from the input point. This family has the following parameters: , .

Webto control some of the metadata used for clustering. TLSH based clustering is less susceptible to such attacks as the TLSH hash digest is computed using the whole byte stream [14]. A comparative analysis of several clustering techniques for malware based on different distance and evaluation metrics is presented in [15], [16]. Webto constraints that are close to each other under tree edit distance, we call it Tree Locality-Sensitive Hash (TLSH). To test TLSH, the GNU Coreutils [2] were symbolically executed. Two sets of experiments were performed. In the ﬁrst, the Coreutils were symbolically executed with no state merging, and the queries sent to the solver were logged.
