Abstract
Network users apply encryption to send and receive data securely. Since ciphertext can be encrypted and decrypted only by lawful users, third parties do not have the ability to know the content of an encrypted message. However, a secret key is uesed for encryption, and if the secret key is lost or corrupted, there is a problem that the encrypted text cannot be decrypted. Additionally, malicious use of this encryption will cause problems. If encryption is used maliciously, the government cannot prevent criminal activity. Because of this law enforcement agencies need support for lawful interception to decrypt criminals or suspect’s ciphertexts. We need a key recovery system that can safely recover these secret keys or decrypt messages for lawful interception. There are two types of key recovery systems, a key escrow method and a key encapsulation method. This paper proposes secure schemes using key encapsulation. The key encapsulation method requires the key information used in the ciphertext, and the key information can be obtained from the KRF (Key Recovery Field). The obtained key can be used to decrypt the ciphertext. however, various security threats exist in key recovery system. Such as forgery and alteration of KRF, single point of failure, inability to recover keys, and collusion attacks. To solve these problems, we propose secure encapsulation schemes based on key recovery system.
