....any 2 k lg n. A hash chain is obtained by repeatedly applying a one way hash function, starting with a secret seed. There are a number cryptographic applications, including password authentication [10] micropayments [13] forward secure signatures [7, 9] and broadcast authentication protocol [11]. Our results enable e ective implementation with arbitrary memory size. 3 The list pebbling algorithm extends to directed trees and general directed graphs. Applications include the e ective implementation of the parent function ( for XML trees, and e ective graph traversals with ....

As a particular case, by keeping lg n hash values, the time to obtain a preceding hash value is O(lg n) The cryptographic applications of hash chain include password authentication [10] micro payments [13] forward secure signatures [7, 9] and broadcast authentication protocol [11]. Such applications and others can bene t from ecient hash chain processing, especially in memory challenged platforms such as smart cards. 7 Traversals of Trees and other graphs We discuss implementations for other linked structures.

....must be computationally inexpensive to verify. Second, it must be short and not require large payloads. Third, it must not depend on secrets stored on motes. BiBa is an example of a mechanism that shows promise, although it still has limitations (a finite number of messages can be signed safely) [11]. 11. THE QUICK We choose to go to the moon in this decade and do the other things, not because they are easy but because they are hard. John F. Kennedy, 1962 By making smart environments possible, sensor networks will fundamentally change the way we live. Biogeochemistry networks will help ....

....(in which case the proof of security no longer holds) An interesting feature of our lower bound for signature schemes is that it bounds the e#ciency of the verification algorithm. There are several practical applications that call for signature schemes with e#cient verification algorithms (e.g. [19]) especially when the client who is verifying signatures is less e#cient that the server who generates them. Our result indicates that there is little hope of improving current schemes based simply on one way permutations. 4 1.3 Open Problems Our lower bound for encryption matches the ....

....1 signatures, and can only sign a xed number of messages per public key. We review the merits and drawbacks of one time signature schemes in Section 7. The recently proposed bins and balls (BiBa) signature is a promising new approach to mitigate some of the drawbacks of one time signatures [23]. We review BiBa in Section 2. In Section 3 we present an abstract framework for these types of signatures, which allows us to present new approaches in Section 4 that are more secure. Our framework also allows us to analyze the security of these signature schemes (see Section 5) we nd that the ....
