difference between secret and public keys. Encryption can be a useful deterrent in keeping sensitive information out of the hands of those not authorized and for maintaining the security of a network. Some encryption schemes utilize a secret key and a public key. Each person on the protected network has both a public and a secret key. Everyone who wants to be able to send encrypted information to another person on the network uses the public key. The recipient then uses a secret key to decrypt the information

antispyware software combats intrusive and harmful spyware programs. Encryption‚ the coding and scrambling of messages‚ is a widely used technology for securing electronic transmissions over unprotected networks. Digital certificates combined with public key encryption provide further protection of electronic transactions by authenticating a user’s identity. Companies can use fault-tolerant computer systems or create high-availability computing environments to make sure that their information systems

two-factor authentication? Generally‚ Two-factor authentication requires two forms of authentication (Panko‚ 117). For example most of the online banking today requires you to login with username/password and also identify security key or security image as additional key. According to the Federal Financial Institution Examination Council 2005 required bank to use at least two-factor authentication. Two-factor authentication utilizes two or more factors to verify customer identify and these two factors

Diffie- Hellman key exchange (DHKE) is the earliest public key exchange protocol‚ it allows prior shared secret key irrespective of past and future keys used in many security protocols. Diffie Hellman Key exchange protocol may be used for initial authentication in Kerberos V5(DHAUTH). The axioms presented in this paper are used in protocol composition logic (PCL). Three innovative ideas presented are essential for formal proofs for DHAUTH.(i) Bugs in DH axiom are fixed (ii) The secrecy conditions

The use of digital certificates and the public key infrastructure (PKI) has emerged as the de facto standard for conducting secure transaction over the public internet. It has become increasing clear that the security infrastructure on which most of e-commerce is based is actually quite fragile. This paper will focus on the framework surrounding the usage of digital certificates and
