Abstract: Visa 3-D Secure is an e-payment system based on the integration of SSL/TLS with the three-domain architecture. It employs cryptographic techniques to secure communication links among participants in e-commerce transactions and also provides credit card verification via Visa Secure Server. Although several security vulnerabilities can be addressed, spoofing attacks are still effective and can be considered as potential threats to Visa 3-D Secure. Threats of spoofing and impersonation have become more effective due to advances in computing and communications technologies. However, security mechanisms incompatible with the past e-payment infrastructure are also enabled by these technological advances. PKI-based authentications used in the SET scheme can be considerable in the current era for enhancing the security of Visa 3-D Secure against spoofing attacks.

Abstract: Grammatical Evolution (GE), which is one of the evolutionary computations, aims to find function, program or program segment satisfying the design objective. This paper describes the improvement of the Grammatical Evolution according to Stochastic Schemata Exploiter (GE-SSE) and its application to symbolic regression problem. Firstly, GE-SSE is compared with original GE in symbolic regression problem. The resultsshow that GE-SSE has faster convergence property than original GE. Secondly, GE-SSE is applied for the stock price prediction as the actual application of the GE-SSE.
