چکیده

How to deal with large tightness gaps in security proofs is a vexing issue in cryptography. Even when analyzing protocols that are of practical importance, leading researchers often fail to treat this question with the seriousness that it deserves. We discuss nontightness in connection with complexity leveraging, HMAC, lattice-based cryptography, identity-based encryption, and hybrid encryption.

Another Look at Tightness

We examine a natural, but non-tight, reductionist security proof for deterministic message authentication code (MAC) schemes in the multi-user setting. If security parameters for the MAC scheme are selected without accounting for the non-tightness in the reduction, then the MAC scheme is shown to provide a level of security that is less than desirable in the multi-user setting. We find similar ...

The Exact Security of Pairing Based Encryption and Signature Schemes

Bilinear pairings have been intensively used in the design of cryptographic protocols during the last few years. For instance, short signatures and non-interactive key exchange protocols have been designed with them, and they appear as a key component for identity-based cryptography. Focusing on encryption and signature schemes built on bilinear pairings, we look at the security reductions of s...

Verifiable Security of Boneh-Franklin Identity-Based Encryption

Identity-based encryption (IBE) allows one party to send ciphered messages to another using an arbitrary identity string as an encryption key. Since IBE does not require prior generation and distribution of keys, it greatly simplifies key management in public-key cryptography. Although the concept of IBE was introduced by Shamir in 1981, constructing a practical IBE scheme remained an open prob...
