Correcting flaws in Mitchell's analysis of EPBC
نویسندگان
چکیده
Efficient error-Propagating Block Chaining (EPBC) is a block cipher mode intended to simultaneously provide both confidentiality and integrity protection for messages. Mitchell pointed out a weakness in EPBC and claimed that this permits a forgery attack. This paper corrects a flaw in Mitchell’s analysis and shows that the attack is no better than brute force of the integrity check vector.

متن کاملEecient Error-propagating Block Chaining
This document presents EPBC, EEcient Error-Propagating Block Chaining, a new and eecient block encryption mode using both plaintext and ciphertext feedback. This encryption mode is similar to another one, IOBC, and was likewise designed to propagate erroneous decryptions of tampered blocks of ciphered data to all following blocks, hence allowing to validate the integrity of that data using a pr...
متن کاملThe neurologic content of S. Weir Mitchell's fiction.
BACKGROUND Silas Weir Mitchell (1829 to 1914), one of the most important neurologists in American Medicine, was known for his seminal work on the phantom limb syndrome, causalgia, and nerve injuries. He was also a prolific writer of novels and short stories. The neurologic content of this fiction has not been studied. OBJECTIVE To assess the extent that references to neurologic topics were pr...

We used lightweight formal modeling and automatic analysis to explore and correct the design and implementation of the Intentional Naming System (INS). INS is a new scheme for resource discovery and service location in dynamic networks. We constructed a model of INS in Alloy, a lightweight relational notation, and analyzed it with the Alloy Analyzer (AA), a fully automatic simulation and checki...
