Recently, numerous leakage-resilient cryptographic schemes have been proposed to resist side-channel attacks which adopt several properties resulting from practical implementations of cryptographic protocols/schemes to leak partial information of secret (or private) keys. Certificateless public key cryptography solves both certificate management problem in conventional public key cryptography and...
Security mechanisms in the traditional cryptography have been modeled under the assumption that secret values (keys) are completely hidden to an adversary. Indeed, a number of side‐channel attacks (e.g., timing, power, fault, etc.) have been demonstrated to obtain partial information about secret keys. Leakage‐resilient cryptography is a countermeasure to withstand side‐channel attacks. Recently,...
Many group-oriented applications and multicast communications often need to verify which group members have sent/received a message. However, individual verification of signed messages would require a significant computation cost. A secure signature scheme with supporting variant batch verifications extremely improves performance. In 2003, Cha and Cheon proposed an efficient identity (ID)-based signature...
In a client-server network environment, a mutual authentication and key exchange scheme is an important security mechanism to provide two parties with the property that they can authenticate each other's identity while they may construct a common session key. With rapid growth of mobile wireless networks, the computational cost on the client side with low power computing devices is a critical factor...
