Process for data confidentiality using probabilistic cryptographic technique

摘要

Present invention provides a model for data confidentiality using probabilistic cryptographic technique which is adoptable to any type of data. The data confidentiality protects data from unauthorized access. The Cryptographic mechanism provides confidentiality by encrypting data. For this first the data is converted into equivalent numeric values then the numeric values are encrypted using probabilistic cryptographic technique. The resultant numeric values of encryption process are converted into equivalent data.The probabilistic symmetric key model is linear transformation based cryptosystem using sub key groups. This is secure and efficient as the key size is reduced from n x n to n.
