ABSTRACT
With the wide application of computer network and intelligent terminal, the application of blockchain technology is rapidly popularized, and the corresponding information security issues become increasingly important. This paper introduces the data encryption standard DES of symmetric encryption algorithm, and discusses the public-key infrastructure system PKI. It is a third-party platform to ensure the security of information during transmission, mainly responsible for issuing certificates with digital signature of CA center and managing public and private-keys needed in RSA algorithm. Several asymmetric encryption algorithms are studied, focusing on RSA asymmetric encryption algorithm, and the method of encrypting public-key decryption with private-key is designed and implemented to solve the problem of information authenticity identification, i.e., identity authentication namely identity authentication. RSA public-key generation, information encryption and decryption are designed, and RSA key generator module, encryption module and decryption module are realized. The results show that RSA algorithm is feasible and safe in blockchain scene.

Multi-use unidirectional identity-based proxy re-encryption from hierarchical identity-based encryption
At ACNS 2007, Ateniese and Green proposed the concept of ID-based proxy re-encryption (IBPRE), where a semi-trusted proxy with some information (a.k.a. re-encryption key), can transform a ciphertext under an identity to another ciphertext under another ...
Proxy re-encryption systems for identity-based encryption
Pairing'07: Proceedings of the First international conference on Pairing-Based CryptographyA proxy re-encryption system allows the proxy to transform ciphertexts encrypted under Alice's public key into the different ciphertexts that can be decrypted by Bob's secret key. In this paper, we propose new proxy re-encryption systems; one for the ...
Identity-based proxy re-encryption version 2
Proxy re-encryption (PRE) enables an authorized proxy to convert a ciphertext under Alice's public key into a ciphertext under Bob's public key without exposing the encrypted message. In existing PRE systems, the original ciphertexts and the re-...
