On a Hybrid Cryptography System for Data Using Advanced Encryption Scheme (AES) and Ron Rivest Shamir Adleman (RSA) Algorithms

Nowadays, the use of information technology has taken over so many sectors. The survivals of many organizations are based on the information that is received or sent out. Due to the dependency on an unsecure communication network, some information that is confidential to the organization is revealed to an unauthorized user and this has necessitated the need for data security. This research work therefore made use of two algorithms for data cryptography to produce a more secure hybrid system. To achieve this aim, Advanced Encryption Scheme algorithm is used to encrypt a message and the secret key of Advanced Encryption is in turn encrypted using Ron Rivest Adi Shamir Leonard Adleman algorithm. This does not only produce a more secure method of data encryption, but also help to solve the problem of key sharing. The result shows that the hybrid Cryptographic sys tem is able to prevent data from unauthorised user.
