The most relevant vulnerabilities of OPERA Phase1 specification that have been detected are the following:
Vulnerability 1: It uses DES [6] with a 56/64 bit key which has been reported to be breakable. It has even been phased out by FIPS (Federal Inbation Processing Standards). Brute force attacks as well as other attacks are feasible. Vulnerability 2: Admission control is only based on MAC addresses. Since these addresses are necessarily sent in the b over the PLC channel, they can be supplanted. Hijacking and identity usurpation are easy to deploy.
Vulnerability 3: There is no mutual authentication. There is no provision to authenticate masters. A malicious masterand man-in-the-middle attacks are possible.
Vulnerability 4: The OPERA1 proposal does not contain any security Message Integrity Check (MIC) that could preserve data against tampering. Vulnerability 5: Channel Estimation MPDUs are never encrypted and include no MIC. Thus they can be manipulated to cause a DoS attack.
Vulnerability 6: Another possible data integrity attack is just to change the b of different blocks in the payload. This would be unnoticed due to the independent ciphering of each block. It is a permutation attack.
Vulnerability 7: It uses Diffie-Hellman algorithm without any protection against Man-in-the Middle attack. Although this may seem a big number of vulnerabilities of the OPERA Phase1 specification, the situation is common with other technologies, the most relevant of them being the early IEEE802.11 security specification
