In the current scenario so many advanced techniques are finding a way as a substitute for complex DFT - based OFDM system. One of such type of technique is Discrete Hartley Transform. The requirement of only real arithmetic computations for the proposed technique makes it more advantageous in terms of ...Download Now
In Ciphertext-Policy Attribute Based Encryption (CP-ABE), attributes are attached to the user's secret key and access policy is attached to the ciphertext. If attributes in the secret key of a user satisfy the policy then only the genuine user can decrypt the ciphertext. However, such scenario also necessitates periodic updating ...Download Now
Ciphertext Policy-Attribute Based Encryption (CP-ABE) is a technique in which user with secret key containing attributes, only able to decrypt the message if the attributes in the policy match with the attributes in secret key. The existing methods that use reasonably computable decryption policies produce the ciphertext of size at ...Download Now
Today's wireless networks are vulnerable in many ways including illegal use, unauthorized access, denial of service attacks, eavesdropping so called war chalking. These problems are one of the main issues for wider uses of wireless network. On wired network intruder can access by wire but in wireless it has possibilities ...Download Now
