Certificateless public key cryptography (CL-PKC) is a useful method in order to solve the problems of traditional public key infrastructure (i.e., large amount of computation, storage and communication costs for managing certificates) and ID-based public key cryptography (i.e., key escrow problem), simultaneously. A signcryption scheme is an important primitive in cryptographic protocols which ...

In this paper, we present a construction of (n, k, d,m) secure regenerating codes for distributed storage systems against eavesdroppers that can observe either data stored in at most m storage nodes or downloaded data for repairing at most m failed nodes in a network where m < k ≤ d ≤ n − 1. The (n, k, d,m) secure regenerating code is based on an (n, k, d) minimum bandwidth regenerating (MBR) c...

In every mythological story, a quest for immortality and eternality depicts man’s inner fervor for unity with gods and the supreme power. Man seeks full immersion in life and longs for immortality at the same time. In other words, he wants to live both in time and in eternity. The desire for eternity in man shows his ceaseless struggle with time, and even more so an intense fight with death to ...
