Random numbers are critical in every cryptographic fields. They can be used as cryptographic key, seed, nonce, initialization vector, etc. In this paper, new (pseudo) random number generator (PRNG or RNG) based on computer's source is proposed. The principle of method consist in collecting (nearly) random sources produced from computer and used it as seed for (pseudo) random number generation. Random...
Key management, particularly, key generation is one of the important processes in information security. Key generation techniques are variously and selecting one of them or creating new key generation include which types of requirements are also difficult. This paper addresses factors to compare key generation techniques and these factors are used as requirements for key generators.
Key management, particularly, biometric cryptosystem is an exciting field in the system security domain. The challenges associated with this domain need to be addressed in detail since the security of the biometric template is itself a big challenge. Biometric template once lost or copied cannot be changed like simple password. This paper summarizes and discusses major challenges of biometric cryptosystem;...
