Standard security notions for encryption schemes do not guarantee any security if the encrypted messages depend on the secret key. Yet it is exactly the stronger notion of security...
- Many researchers have considered security policy management, including how to configure policies manually and even how to automatically generate security policies based on securi...
The UNIX operating system was developed in a friendly, collaborative environment without any particular predefined objectives. As it entered less friendly environments, expanded it...
We propose (T, N) multi-ciphertext scheme for symmetric encryption. The scheme encrypts a message into N distinct ciphertexts. The knowledge of the symmetric key allows decryption ...
The paper presents an effective mobile-to-mobile payment system. A mobile phone with or without SIM card is enabled as an EMV payment instrument and is linked to a debit or credit...
