Due to the mobility of users in an organization,inclusion of dynamic attributes such as time and location becomes the major challenge in Ciphertext-policy Attribute-Based Encryption(Cp-ABE).By considering this challenge;we focus to present dynamic time and location information in Cp-ABE with ***ﬁrst,along with the set of attributes of the users,their corre-sponding location is also *** is used to encode the latitude and longitude of the user’s ***,decrypt time period and access time period of users are deﬁned using the new time tree(NTT)*** NTT sets the encrypted duration of the encrypted data and the valid access time of the private key on the data user’s private ***,single authorization of attribute authority(AA)is extended as multi authorization for enhancing the effectiveness of key *** results depict that the proposed Cp-ABE achieves better encryption time,decryption time,security level and memory ***,encryption time and decryption time of the proposed Cp-ABE are reduced to 19%and 16%than that of existing Cp-ABE scheme.
