Forward-Security in Private-Key Cryptography
This paper provides a comprehensive treatment of forward-security in the context of sharedkey based cryptographic primitives, as a practical means to mitigate the damage caused by key-exposure. We provide definitions of security, practical proven-secure constructions, and applications for the main primitives in this area. We identify forward-secure pseudorandom bit generators as the central pri...
متن کاملBiometric Database Protection using Public Key Cryptography
With the increasing need for stringent security measures in recent times, biometric systems have assumed greater importance for information security systems. For biometric systems to offer reliable security, they themselves have to satisfy high security requirements to ensure invulnerability. This paper proposes two different approaches based on RSA and Elliptic curve cryptography for database ...
متن کاملDistributed Private-Key Generators for Identity-Based Cryptography
An identity-based encryption (IBE) scheme can greatly reduce the complexity of sending encrypted messages. However, an IBE scheme necessarily requires a private-key generator (PKG), which can create private keys for clients, and so can passively eavesdrop on all encrypted communications. Although a distributed PKG has been suggested as a way to mitigate this key escrow problem for Boneh and Fra...
متن کاملAsynchronous Distributed Private-Key Generators for Identity-Based Cryptography
An identity-based encryption (IBE) scheme can greatly reduce the complexity of sending encrypted messages over the Internet. However, an IBE scheme necessarily requires a private-key generator (PKG), which can create private keys for clients, and so can passively eavesdrop on all encrypted communications. Although a distributed PKG has been suggested as a way to mitigate this problem for Boneh ...
متن کاملCryptography. key exchange, public key
General cryptographic schemes are presented where keys can be one-time or ephemeral. Processes for key exchange are derived. Public key cryptographic schemes based on the new systems are established. Authentication and signature schemes are easy to implement. The schemes may be integrated with error-correcting coding schemes so that encryption/coding and decryption/decoding may be done simultan...
