  • Method of enciphered traffic inspection with trapdoors provided
    Patent number: 10812506
    Abstract: A method for detecting intrusions uses a searchable enciphering algorithm and includes: generating a trap bypass key for a security device, which is able to determine keywords characteristic of intrusions, generating by the security device a trap for each keyword by using the trap bypass key; providing the traps to an intrusions detection device; intercepting by the detection device character strings sent on the network by a sender and enciphered with a public key of a receiver; applying by the detection device a test procedure on the character strings enciphered using the traps; and detecting an intrusion on the network if there exists according to the test procedure an enciphered character string representative of a cipher of a keyword.
