Remote EAP-SIM authentication has an overwhelming impact on the authentication delay. RADIUS protocol can be used for local authentication which reduces authentication latency. However, in case of EAP-SIM authentication, where triplets are to be retrieved from a remote authentication gateway (AuC), this does not help much. An Improved EAP-SIM authentication method was proposed in [2]. In this p...

At present, the proposed authentication schemes can be classified into three categories. The first category is the watermarking authentication schemes in which the watermark is independent of the multimedia content. The second category is the signature-based authentication schemes in which the signature is generated by the multimedia content and is not embedded into the multimedia content. The ...

This paper presents an evolution of authentication mechanisms from textual passwords to graphical authentication mechanisms. For security concerns password must be protected from the unauthorized users. Authentication and authorization is necessary for essential data, this requires authentication mechanisms. An important goal for authentication is user has easy to memorize their passwords and r...

Quantitative histology of the descended testis of unilateral cryptorchid bucks was compared with testis of normal bucks to evaluate the reproductive potentials of the scrotal testis in unilateral cryptorchids, using light microscopy techniques. The contralateral scrotal testes of the unilateral cryptorchids and the testes of the normal bucks contained profiles of seminiferous epithelium and eac...
