Some other system-specific security measures are also proposed. Although these are examples only, the techniques discussed can also be used in and provide reference for other remote control systems.展开更多

Through the Kerberos authentication protocol, a client can prove its identity to a server (and vice versa) across an insecure network connection such as on Internet. In this comparative research paper, the Kerberos authentication protocol is extended and strengthened using x.509 with the integration of newer authentication system which is compared with previous authentication systems. In addition to this, RSA encryption mechanism used to provide authentication and security for the most communication systems replaced with Elliptic Curve Cryptography (ECC) encryption in Kerberos during authentication progress through simulation to expose possible efficient alternatives for key generation and to enhance security.展开更多

There are many developed methods to overcome thisproblem. Identity authentication is one of these important measures. The authentication methods oftraditional symmetric cryptogram systems and asymmetric cryptogram systems have both advantages anddefects. This paper brings forward a Mixed Encryption Model for Authentication ( MEMA), which hasobvious advantages compared to the two traditional methods. MEMA model can be used widely in openingnetwork environment such as mobile agent systems, multi-agents security safeguard systems and othersituations in which identity authentication of users are needed. At last, the paper also presentsthe MEMA model's structure and implementation of an experimental system.展开更多

SMS messages are one of the popular ways of communication. The aim therefore is to design a software for end to end encryption short message service (SMS) that can conceal message while on transit to another mobile device using Hybrid Cipher Algorithm on Android Operating System and implement it for security of mobile SMS. Hybrid encryption incorporates a combination of asymmetric and symmetric encryption to benefit from the strengths of each form of encryption. Various encryption algorithms have been discussed. Secondary sources were employed in gathering useful data. In this research work three methodologies are employed—Structured System Analysis Design Methodology (SSADM), Object Oriented Analysis Design Methodology (OOADM) and prototyping. With the help of the three cryptographic algorithms employed—Message digest 5 (MD5), Blowfish and Rivest-Shamir Adleman (RSA);integrity, confidentiality, authentication and security of messages were achieved. The messages encrypted by developed application are also resistant to brute force attack. The implementing programs were coded in Java.展开更多
