By comparing a hash value and a module name in the saved list, it checks whether a module has a manufacturer's signature.
Generate and broadcast hash ID: Every packet broadcasted by cluster members must include a control word, which is a hash value returned by a certain hash function, e.g., the nonreversible SHA hash function, from the ID of this cluster member.
A hash value, generated by a hash function, is given by, in which is a variable-length message and is the hash value with a fixed length.
In the SPS (Generic Secure Provenance) scheme [10], the provenance of a node with respect to a data item (D_i) is encoded as (P_i= langle n_i, hash(D_i), C_i rangle ), where (n_i) is the node ID; (hash(D_i)) is a cryptographic hash of the data item (D_i); (C_i= {hash(n_i,hash(D_i) Vert C_{i-1})}_{k_i}), i.e., (C_i) is a hash value signed by (n_i) with its encryption key (k_i).
Biomedical signature processing module generates a hash value based on new biomedical data of a user measured by a PHD.
A hash value is calculated consistently for each pattern encountered.
Subsequently, a hash value Hash (Name, Attr, V ec(T ||V ec(C)) is generated, where Name is the user's name, Attr are public attributes of the user and Hash is a hash function.
The output of a hash function, such as h(x), is called a hash value.
The biomedical signature of a user is a hash value calculated from the highest values and the lowest values of the biomedical data, which is obtained by the PHDs the user carries for a certain period of time.
A one-way hash function, such as the Secure Hash Algorithm (SHA) [ 22], transforms a string or other series of bytes into a new, fixed-length string (a hash value) in such as way that it is impossible, or at least extremely difficult, to discover the value of the original string from the hash value.
