Using time to determine a hash extension

A method for a computing device to derive a node-selectable portion of a network address from a public key of the computing device, the method comprising:

• a) computing by a computing device a plurality of hash values using a second hash function until a stop condition, the stop condition including computing the plurality of hash values for a time limit specified by a time parameter, an input for each hash value in the plurality of hash values including a concatenation of a public key and a modifier, wherein the modifier is included in at least one cryptographically generated address parameter and is modified during repeating of computing operations;
• b) terminating the computing operation when the stop condition is met, the stop condition further comprising a probability below a threshold probability that a more secure hash value will be generated within a remaining time of the time limit;
• c) selecting by the computing device a second hash value from the plurality of hash values;
• d) generating by the computing device a hash indicator indicating the selected second hash value;
• e) computing by the computing device a first hash value using a first hash function, the input to the first hash function including a concatenation of the public key and the modifier;
• f) setting at least a portion of a node-selectable portion of a network address of the computing device to a portion of the first hash value.

One or more computer readable storage media having computer executable components being executed by a processor to generate a network address of a computing device, comprising:

• a) means for generating a plurality of interim hash values using a second hash function until a stop condition, the stop condition including computing the plurality of interim hash values for a time limit specified by a time parameter, each interim hash value having an input including a concatenation of a public key and a modifier, wherein the modifier is included in at least one cryptographically generated address parameter and is modified during repeating of computing operations;
• b) means for terminating the means for generating the plurality of interim hash values when the stop condition is met, the stop condition further comprising a probability below a threshold probability that a more secure hash value will be generated within a remaining time of the time limit;
• c) means for selecting a second hash value from the plurality of interim hash values;
• d) means for generating a hash indicator indicating the selected second hash value;
• e) means for computing a first hash value, the input to the first hash function including a concatenation of the public key and the modifier;
• and
• f) means for generating a network address of the computing device based on at least a portion of the first hash value.
