Abstract
An extensible cryptographically generated network address may be generated by forming at least a portion of the network address as a portion of a first hash value. The first hash value may be formed by generating a plurality of hash values by hashing a concatenation of a public key and a modifier using a second hash function until a stop condition. The stop condition may include computing the plurality of hash values for a period of time specified by a time parameter. A second hash value may be selected from the plurality of hash values, and the modifier used to compute that hash value may be stored. A hash indicator may be generated which indicates the selected second hash value. The first hash value may be generated as a hash of a concatenation of at least the public key and the modifier. At least a portion of the node-selectable portion of the network address may include at least a portion of the first hash value.
