WebMAC) for streaming-accessed chunks and fine-grain MAC (i.e., per block MAC) for random-accessed ones, to reduce the MAC access bandwidth. To support dual-granularity MACs, we reserve space for both MACs and access only one of them at runtime based on the access pattern.

WebThis constrained PRF has already found many interesting applications. Unfortunately, the existing security proofs only show selective security (by a reduction to the security of the underlying PRG). To achieve full security, one has to use complexity leveraging, which loses an exponential factor 2 N in security, where N is the input length. WebIn this course you will learn the inner workings of cryptographic systems and how to correctly use them in real-world applications. The course begins with a detailed discussion of how two parties who have a shared secret key can communicate securely when a powerful adversary eavesdrops and tampers with traffic.

Webshow, basically tight proof for the PRF-security of NMACf assuming only that f is a PRF: If f is an "-secure PRF against qqueries, then NMACf is roughly ‘q"-secure against qqueries of length at most ‘blocks each. Our actual result is more ne-grained, and expresses the security in terms of both the adaptive and non-adaptive security of f. Webwork based constrained PRFs are proved to have adaptive pseudorandomness in [FKPR14,JKK+17], but the reduction loss is still super-polynomial. Besides, (private) constrained PRFs with adaptive security for various constraints are also proposed in the random oracle model in [BW13,HKKW19,AMN+18].
